RPN
Reverse Polish notation (RPN), also known as Polish postfix notation or simply postfix notation, is a mathematical notation in which operators follow their operands, in contrast to Polish notation (PN), in which operators precede their operands. It does not need any parentheses as long as each operator has a fixed number of operands. The description "Polish" refers to the nationality of logician Jan Łukasiewicz, who invented Polish notation in 1924.
The reverse Polish scheme was proposed in 1954 by Arthur Burks, Don Warren, and Jesse Wright and was independently reinvented by Friedrich L. Bauer and Edsger W. Dijkstra in the early 1960s to reduce computer memory access and use the stack to evaluate expressions. The algorithms and notation for this scheme were extended by the Australian philosopher and computer scientist Charles L. Hamblin in the mid-1950s.
During the 1970s and 1980s, Hewlett-Packard used RPN in all of their desktop and hand-held calculators, and continued to use it in some models into the 2020s. In computer science, reverse Polish notation is used in stack-oriented programming languages such as Forth, STOIC, PostScript, RPL and Joy.
Explanation
In reverse Polish notation, the operators follow their operands; for instance, to add 3 and 4 together, one would write 3 4 + rather than 3 + 4. If there are multiple operations, operators are given immediately after their second operands; so the expression written 3 − 4 + 5 in conventional notation would be written 3 4 − 5 + in reverse Polish notation: 4 is first subtracted from 3, then 5 is added to it. An advantage of reverse Polish notation is that it removes the need for parentheses that are required by infix notation. While 3 − 4 × 5 can also be written 3 − (4 × 5), that means something quite different from (3 − 4) × 5. In reverse Polish notation, the former could be written 3 4 5 × −, which unambiguously means 3 (4 5 ×) − which reduces to 3 20 − (which can further be reduced to -17); the latter could be written 3 4 − 5 × (or 5 3 4 − ×, if keeping similar formatting), which unambiguously means (3 4 −) 5 ×.

The SG-1000, also known as the Sega Game 1000 or Sega Mark I, is a home video game console manufactured by 
Sega and released in Japan, Australia, New Zealand, and other regions. It was Sega's first entry into the home video game hardware business. Introduced in 1983, the SG-1000 was released on the same day that Nintendo released the Family Computer in Japan. The SG-1000 was released in several forms, including the SC-3000 computer and the redesigned SG-1000 II released in 1984. A third iteration of the console, the Sega Mark III, was released in 1985. It provided a custom video display processor over previous iterations and served as the basis for the Master System in 1986, 
Sega's first internationally released console.
Developed in response to a downturn in arcades in 1982, the SG-1000 was created on the advice of Hayao Nakayama, president of Sega Enterprises, Ltd. Shortly after the release, Sega Enterprises was sold to CSK Corporation, which was followed by the release of the SG-1000 II. The SC-3000 and the SG-1000 line both support a library of 76 ROM cartridge games and 29 Sega My Card games, all of which are fully compatible with the Mark III and the Japanese version of the Master System.
SCART (also known as Péritel or Péritélévision, especially in France, 21-pin EuroSCART in marketing by Sharp in Asia, Euroconector in Spain, EuroAV or EXT, or EIA Multiport in the United States, as an EIA interface) is a French-originated standard and associated 21-pin connector for connecting audio-visual (AV) equipment. The name SCART comes from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs, "Radio and Television Receiver Manufacturers' Association", the French organisation that created the connector in the mid-1970s. The related European standard EN 50049 has then been refined and published in 1978 by CENELEC, calling it péritelevision, but it is commonly called by the abbreviation péritel in French.
Schoenherr Gmbh
Schoenherr GmbH, Horb (Germany) was founded in 1974 by Mr. Schoenherr. He invented in 1975 the world’s first Braille element that could display and erase Braille characters. This patented invention was the prerequisite for developing Braille displays which enabled access to the world of computers for the blind. In 1980 Mr. Schoenherr was awarded with the Louis-Braille-Prize and Schoenherr GmbH introduced with the Braillotron TI-30, the first electronic calculator using a refreshable Braille cell for output. In 1981 he was killed in an accident and two years later the company was taken over by the "Deutsche Blindenstudienanstalt", a non-profit-organization in Marburg as EHG GmbH and was the production site for Braille displays. Since 1994 the company re-firmed as EHG Handy Tech Elektronik GmbH.

How to use this unusual calculator
The Sinclair Scientific calculator uses reverse Polish notation (RPN) and scientific notation, so the key sequences are totally different from regular calculators. Numbers automatically have a decimal point inserted; use E to set the exponent. Operations are entered after the number and there is no equals key. Use the up and down arrows to select scientific functions. A display such as 1.2300 01 indicates 1.23*10^1, i.e. 12.3. A few examples:
To divide 17 by 3, enter 1 7 E 1 + 3 ÷
To take the sin of 0.01 radians, enter 0 0 1 ▲ +
To take antilog of .5 (to compute 10^.5), enter 5 E - 1 ▼ ×
Reverse Engineering from Ken Shirriff's blog
Bowmar soon became one of the world's largest producers of electronic calculators, mainly pocket models, for sale by themselves and by other companies such as Sears, Radio Shack, etc. (under their own nameplates). Early Bowmar calculators were made in the USA. In later years some were also made or assembled in Mexico.
Sega Corporation is a Japanese multinational video game developer and publisher headquartered in Shinagawa, Tokyo. Its international branches, Sega of America and Sega Europe, are headquartered in Irvine, California, and London. Sega's arcade division existed as Sega Interactive Co., Ltd. from 2015 to 2020 before it merged with Sega Games to create Sega Corporation with Sega Games as the surviving entity. Sega is a subsidiary of Sega Group Corporation, a part of Sega Sammy Holdings. From 1983 until 2001, Sega also developed video game consoles.
Sega was founded by American businessmen Martin Bromley and Richard Stewart as Nihon Goraku Bussan on June 3, 1960; shortly after, the company acquired the assets of its predecessor, Service Games of Japan. Five years later, the company became known as Sega Enterprises, Ltd., after acquiring Rosen Enterprises, an importer of coin-operated games. Sega developed its first coin-operated game, Periscope, in 1966. Sega was sold to Gulf and Western Industries in 1969. Following a downturn in the arcade business in the early 1980s, Sega began to develop video game consoles, starting with the SG-1000 and Master System but struggled against competitors such as the Nintendo Entertainment System. In 1984, Sega executives David Rosen and Hayao Nakayama led a management buyout of the company with backing from CSK Corporation.

Info:The Silent 700, introduced in 1971, was a line of portable computer terminals manufactured by Texas Instruments in the 1970s and 1980s. Silent 700s printed with a 5 x 7 dot-matrix heating element onto a roll of heat-sensitive paper. Some models were equipped with an integrated acoustic coupler and modem that could receive data at 30 characters per second. Other models could be directly connected to computers at 300 bits/second (bps), and were sometimes used as the System console where a hard copy record of the activities would be retained for a period of time.

Info: The Silent 700, introduced in 1971, was a line of portable computer terminals manufactured by Texas Instruments
in the 1970s and 1980s.
Silent 700s printed with a 5 x 7 dot-matrix heating element onto a roll of heat-sensitive paper. Some models were equipped with an integrated acoustic coupler and modem that could receive data at 30 characters per second. Other models could be directly connected to computers at 300 bits/second (bps), and were sometimes used as the System console where a hard copy record of the activities would be retained for a period of time. The Silent 700s were marketed as being extremely portable and reliable, “designed to use a minimum of moving parts, eliminating wear elements” (Texas Instruments). They included features like a built-in acoustic coupler that allowed the user to call into a remote computer system from any telephone and a built-in thermal printer which would quietly (user reports from the 70’s indicate that “silent” was a stretch) (Hannigan 4) print with a dot-matrix heating element onto thermal paper. Thermal paper was thin paper that was specially coated in heat sensitive material that would change color when exposed to heat, thus giving physical form to the data being transmitted. The Silent 700 models printed data at a speed of 30 characters per second. The 735 model weighed 25 pounds and cost $2,595 (approximately $12,400 in 2019), while the streamlined 745 model weighed only 13 pounds and cost $1995 (approximately $9,500 in 2019) (Texas Instruments).
Silicon Wafer
Silicon Wafer In electronics, a wafer (also called a slice or substrate) is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.
The wafer serves as the substrate for microelectronic devices built in and upon the wafer. It undergoes many microfabrication processes, such as doping, ion implantation, etching, thin-film deposition of various materials, and photolithographic patterning. Finally, the individual microcircuits are separated by wafer dicing and packaged as an integrated circuit.

Here you can see some production scraps. The first photo (left) shows the component ready to be assembled, the second shows the various chips ready to be removed from the tray and placed in the ceramic chip. The three remaining photos show the various chips ready to be cut. I have to thank Francesco for giving me the opportunity to show these pieces!
This 950g crystalline (105 x 50 mm) silicon ingot is a high-purity, technical-grade sample produced using the "Czochralski method" a technique commonly employed in the manufacture of semiconductors and microchips. It originates from Silicon Valley (USA), with final processing carried out in Poland. Silicon fragments in this form are rarely available outside of industrial manufacturing settings, making this item an exceptional collector's or display piece. Its metallic luster and regular crystalline structure make it ideal for scientific demonstrations, educational activities, and materials research.

Year: 1978
Chip: TMS1000 / MP3226
Info:The Simon is an electronic game of short-term memory skill invented by Ralph H. Baer and Howard J. Morrison, working for toy design firm Marvin Glass and Associates, with software programming by Lenny Cope. The device creates a series of tones and lights and requires a user to repeat the sequence. If the user succeeds, the series becomes progressively longer and more complex. Once the user fails or the time limit runs out, the game is over. The original version was manufactured and distributed by Milton Bradley and later by Hasbro after it took over Milton Bradley. Much of the assembly language code was written by Charles Kapps, who taught computer science at Temple University and also wrote one of the first books on the theory of computer programming. Simon was launched in 1978 at Studio 54 in New York City and was an immediate success, becoming a pop culture symbol of the 1970s and 1980s.
The Black Watch is an electronic wristwatch launched in September 1975 by Sinclair Radionics. It cost £24.95 ready-built, but was also available for £17.95
, as a kit.[These prices are equivalent to around £190 and £140 respectively in 2021, when adjusted for inflation.
The Black Watch was supplied with a plastic band as standard, with a black stainless steel bracelet available as an extra at £2.00.
I'm a fan of watches especially Texas Instruments, but when I come across watches like this 1975 Sinclair black watch I don't let it get away. Unfortunately he had problems with corrosion from the usual button cell batteries.
I solved, as often happens with objects with corroded pcb, to use 0.03 mm copper sheets. You have to clean up the damaged part and copy the part of
the PCB to be reproduced on a transparent sheet, copy it on the copper sheet and cut it.
Then glue the pcb reproduced with silicone or with glue for gold leaf, I prefer the latter. Put it all together and you're done.
Wikipedia Sinclair Black Watch
The Sinclair QL (for Quantum Leap) is a personal computer launched by Sinclair Research in 1984, as an upper-end counterpart to the ZX Spectrum.
The QL was aimed at the serious home user and professional and executive users markets from small to medium-sized businesses and higher educational establishments, but failed to achieve commercial success.
While the ZX Spectrum has an 8-bit Zilog Z80 as the CPU, the QL uses a Motorola 68008. The 68008 is a member of the Motorola 68000 family with 32-bit internal data registers, but an 8-bit external data bus.
TroubleShooting
Power-on problem: White screen, possible faulty RAM memory.
I recommend installing the "Minerva" eprom, FW developed to give a new basic, but above all to help turn on the QL. Remove the two original EPROMs and insert the socket with the new EPROM.
in case of error a screen like this will appear. This window tells us that the first line is the value that is written to RAM, the second line is the read value, the third is the memory address.
In this case, a little program developed by XAD at this address comes to our aid: https://www.nightfallcrew.com/minervaram/index.php
We enter the data and we will have an indication of the faulty RAM. In our case the U4.
IF < $30000 (ADDRESS) = IC8 ,IC7 ,IC6 ,IC5 ,IC4 ,IC3 ,IC2 ,IC1
IF > $30000 (ADDRESS) = IC16 ,IC15 ,IC14 ,IC13 ,IC12 ,IC11 ,IC10 ,IC9
IF > $40000 Faulty ram is in expansion memory.
Here we can see the operation after the repair.
Sinclair Radionics
In 1972, Radionics launched its first electronic calculator, the Executive, which was considerably smaller than its competitors' by the use of hearing-aid-sized batteries. What had made this possible was it had been discovered that there was considerable latency in the display and memory and that, with the addition of a timer, power could be withheld from these battery-draining components for much of the time, thus greatly extending battery life.
During the majority of the 1970s, Sinclair focused on building the most affordable pocket calculators with the best design. In 1972 Sinclair released the world's first slim-line pocket calculator, the Sinclair Executive, for £79.95. The calculator only included basic maths functions, and the LED display required much power. It is often credited as being the world's first attractively styled calculator that did not require mains power to be used like prior calculators. The Executive was a phenomenal success, earning Sinclair £1.8m in profit. In 1973 the slightly larger Sinclair Cambridge was introduced at a far cheaper price of £29.95 + VAT. A cheaper Executive was also launched shortly after. In addition to expanding the Cambridge range, the Sinclair Scientific was launched in 1975. It was a scientific pocket calculator for the very competitive price of £49.95. In 1977 a revised model, the "Scientific Programmable", was released at £29.95. The Scientific Programmable Mark 2 was later released, reducing the price to £17.22.
In 1975, Sinclair Radionics launched the Oxford range of briefcase calculators. Sinclair also attempted to capture the top-end calculator market with the Sinclair Sovereign, available in plated gold or silver. The calculator was critically acclaimed for its excellent engineering and design and enjoyed short success. Final attempts at the mass-market for calculators, the Sinclair Enterprise and the President, did not sell well.
In 1974, Radionics launched the DM1 digital multimeter. Such scientific instruments were to form a quiet backbone of Radionics business for the rest of its existence. In marked contrast to the rest of the Sinclair range, the instruments gained a reputation for reliable conventionality rather than often unreliable idiosyncrasy.
Slide Rule Decline
Texas Instruments (TI) invented the first integrated circuit in 1958, courtesy of TI inventor Jack Kilby, and the handheld calculator, a prototype called the "Cal Tech," invented by TI's Jerry Merryman in 1967. However, the first handheld scientific calculator or "slide rule" offered to the public was Hewlett-Packard's. The HP-35 was named by Bill Hewlett for the number of keys on the calculator, and in 1972, the year the slide rule as we know it began to decline, Hewlett-Packard announced the HP-35 as a fast, highly accurate electronic slide rule with solid-state memory similar to a computer. Even though they had a launch price of $395.00, engineers and engineering students flocked to stores to buy them (much like the iPod craze today). Some students even sold their cars to afford one. However, because the exorbitant cost of producing HP calculators made them unaffordable to 90% of the general population, the slide rule remained popular and useful for another four years. According to the ISRM, the official death date of the slide rule was June 13, 1976, when Texas Instruments introduced the TI-30 single-chip slide rule scientific calculator for $24.95, which was below the cost of a comparable slide rule. There was no longer any cost advantage for new students, technicians, and engineers to purchase a slide rule, since everyone could afford the TI-30. Coincidentally, just one month later, on July 11, 1976, Kueffel & Esser, the oldest and largest slide rule manufacturer in the United States, produced its last slide rule. In the following month of August 1976, Pickett Industries followed suit, discontinuing all production of its slide rules.
Texas Instruments SN7400
The 7400 series is a popular family of transistor-transistor logic (TTL) integrated circuits (ICs).
In 1964, Texas Instruments introduced the SN5400 series of logic chips in a ceramic semiconductor package. In 1966, the SN7400 series (composed of four NAND logic gates with 40 transistors) in a low-cost plastic package was introduced, quickly capturing over 50% of the logic chip market and becoming a de facto standard electronic component. Since the introduction of the original bipolar transistor TTL components, pin-compatible components have been introduced with features such as low-power CMOS technology and lower supply voltages. Surface-mount packages exist for several functions of this popular logic family.
In the photo an example of an integrated circuit produced by Texas instruments, the first line indicates the type of integrated circuit SN7400N, the second line indicates the date of construction, the first two numbers indicate the year, the second two numbers indicate the week, therefore, 45th week of 1976. In the nearby photo there is a drawing of how a logic gate of the SN7400N is made
Texas Instruments SN76477
"complex sound generator" is a sound chip produced by Texas Instruments (TI). Th
e chip came to market in 1978, and TI ceased production of the part. A compatible version is identified as ICS76477. The chip is typically used as a sound effects generator in arcade games and toys and for hobby projects. The use of the SN76477 in a musical context is limited by the fact that it was difficult to electronically control the pitch of the produced sound.
Solari Cifra 3
Solari Cifra 3 is the smallest direct reading electromechanical watch, designed by Gino Valle and produced by the Solari company of Udine in the late 1960s. The clock was added to the permanent collection of the Museum of Modern Art in New York (MoMA) in 1967.
«I don't make objects, I establish relationships. I build relationships and define environmental flows in terms of time, such as before, during and after. It is not so much the plots that count as the succession of spaces, the relationships, the transformations, the transition rituals.» (Gino Valle)
Inc. Solari di Udine S.p.A. è una società che opera prevalentemente nel settore dei sistemi a orologeria d'informazione al pubblico, storicamente legatasi al settore dell'orologeria industriale e resasi famosa per l'invenzione dell'orologio a palette e, in generale, dello schermo a palette.
Il 1725 è l'anno ufficiale di fondazione del primo stabilimento produttivo che era collocato a Pesariis, un piccolo paese montano della Carnia; la ditta Fratelli Solari era conosciuta come “Antica e premiata fabbrica di orologi da torre”: infatti, per oltre due secoli, l'impresa produsse orologi da torre e orologi ornamentali da parete.
Nel corso del XIX secolo, l'azienda s'ingrandì costantemente sviluppando la produzione e assumendo molte persone: da attività puramente artigianale diventò gradualmente una realtà industriale; da ditta individuale si trasformò in società: Fratelli Solari & Co. La produzione subì una battuta d'arresto nel 1917 quando i contraccolpi della prima guerra mondiale comportarono la perdita d'importanti strumenti produttivi.

Spectrum Inves +. A clone of the ZX Spectrum+ developed by Investrónica in Spain in 1986, based on the work developed by Investrónica for the ZX Spectrum 128. Released just after Amstrad bought Sinclair Research Ltd, looked much like a normal 48+, but all the inner parts were redesigned. As the ROM was also modified, it has compatibility problems with some games (Bombjack, Commando, Top Gun, etc.).[1] On the rear there was a Kempston joystick connector.
Due to the fact that Invéstronica was the distributor of Sinclair's products in Spain, and because Amstrad already had its own exclusive distributor in Spain (Indescomp, later bought by Amstrad itself), in 1987 Amstrad sued Investrónica to stop the sale of the computer.[2] The court agreed with Amstrad, but the decision was not issued until 1991, when the computer was discontinued as the 8-bit computer market in Spain was dead in favor of 16-bit computers.
On this page you can find the correspondence between the various games that used speech synthesis and the chip used.

Manual:
Info:The extremely rare SR-40 LCD (1981) calculator produced in Brazil is an interesting model, as at first glance it looks very similar to the European version of the TI-30 LCD. However, a few differences set it apart. One of the most noticeable differences concerns the keys: while the European TI-30 LCD features the **N!** (factorial) key, the Brazilian SR-40 LCD has the **x!** key, a detail that might reflect slight variations in functionality or target use. Another notable difference is the design of the battery compartment. The SR-40 LCD uses two AA batteries, but the compartment cover requires a coin to be opened, unlike the sliding cover of the European TI-30 LCD. This feature probably represents an adaptation for greater durability or security in battery replacement. These small variations between the models highlight production differences between different markets, making the SR-40 LCD a particularly rare and interesting piece for vintage calculator collectors.

Manual:
Info:With the SR-51 Texas Instruments began a series of scientific calculators that added statistical functions and conversions to the "usual functions". But none of them are engineered as flawlessly as the SR-51. It was built as a tank to survive decades of use like its close relative SR-50. Compared to previous models, the SR-51 got a keyboard design with white, gray, yellow and orange keys and gave a perspective to later TI calculators. To reduce manufacturing costs and to give a similar look and feel to the SR-52 and SR-56 calculators, the SR-51 was replaced within months with the SR-51A. Logically it is quite rare. However, two different variants are known: this model from an early production batch uses huge yellow characters for the 2 shifted functions, while the later SR-51 sports much finer print.
This rare model had many parts corroded by battery acid, the 7-segment displays completely corroded, the replacement and cleaning of the keyboard can be seen on the side.

Info: Texas Instruments introduced in 1976 with the SR-60 their first high-end programmable desktop calculator. Priced at $1695 and with a footprint of roughly 17" by 14.5" (430 mm * 370 mm) the SR-60 resembled more a computer than a programmable calculator.
Based on the SR-52 and SR-56 series of programmable calculators, the SR-60 integrated a full-sized keyboard with 95 keys, a large alphanumeric display with 20 characters, a thermal dot-matrix printer with 20 characters and a magnetic card reader for saving and loading both programs and data.
One of the main advantages of the SR-60 is the huge memory for data and program, already the base model could hold 480 program steps and 40 memory registers. Two memory expansion modules were available, one implemented with just two small daughter boards holding 5 resp. 3 TMC0599 RAM chips accessible through a bottom panel in the housing. The second memory expansion, a huge printed circuit board (PCB) with a total of 27 TMC0599 RAM chips, was mounted below the keyboard next to the Main PCB.
The SR-60 operates using pure algebraic logic (e.g., problems are presented to the machine as they would be written on paper). The calculator adheres to the PEMDAS (Parenthesis, Exponentiation, Multiplication, Division, Addition, Subtraction) order of precedence. The [(] and [)] keys may be used to group expressions to override the PEMDAS rules as required. Parentheses can be nested up to ten levels deep. The machine calculates and displays results to ten significant digits, and always formats the display to provide maximum accuracy.

Claudio Larini. My interest in the world of information technology was born as soon as I finished high school, before leaving for the university adventure at the Polytechnic of Milan, after having purchased the first issue of a magazine, Micro and Personal Computer in September 1979. So after having consulted the "Market Guide", which was divided between Personal Computers, Programmable Calculators and Microprocessor Boards, and compatibly with the available budget I decided to purchase a programmable calculator.

TroubleShooting 
After finding the SR-60 and checking it, we realized that it wasn't working. We started with the power supply. This power supply provides all power for the individual PCBs, (-20, -15.8, -10, -5 and -19) with an input voltage ranging from -26.5 to -42. At this point we realized that the -15.8 voltage that powers the main PCB was not being supplied.
As expected with these 50 year old objects, the filter capacitors, in this case 10uF, failed, one was shorted, another changed value.
Causing the breakage of three transistors in the power supply, the TIP30 replaced with one from the stock of components we have from the 70s and 80s, in addition to the A1872 replaced with a BC556 and an A2031 replaced with a BC547. We were unable to find the latter the same .

Summit International Corp., Salt Lake City, Utah.Manufactured by NCE Nuclear, made in U.S.A.
In 1971 Ed Price made a prototype hand-held electronic calculator using a carved wooden case and breadboarded electronics.
Nuclear Controls and Electronics (NCE) of Salt Lake City were interested in diversifying and contracted Ed and his calculator. They were marketed by the affiliated Summit International Corporation and a series of generally very small calculators was developed and sold from 1972.
Trans Atlas took over NCE and Summit in 1974, by which time there was a glut of manufacturers in a maturing, low profit market and manufacture of Summit calculators ceased.
Ed Price went on to form a new company, Price Research Associates, which made one characteristically tiny hand-held model.

The SYM-1 is a single board "trainer" computer produced by Synertek Systems in 1975. It was designed by Ray Holt. Originally called the VIM-1 (Versatile Input Monitor), that name was later changed to SYM-1.The SYM-1 is a close copy of the popular MOS Technology KIM-1 system, with which it is compatible to a large extent. Compared to the KIM-1, enhancements include the ability to run on a single +5 volt power supply, an enhanced monitor ROM, three configurable ROM/EPROM sockets, RAM expandable on board to 4 KB, an RS-232 serial port, and a "high speed" (185 bytes/second, the KIM-1 supports about 8 bytes/second) audio cassette storage interface. It also features on-board buffer circuits to ease interfacing to "high voltage or high current" devices.
One capability of the SYM-1 is its ability to allow an oscilloscope to be added to provide a 32 character display under software control. As explained in Chapter 7 of the "SYM Reference Manual", the vertical input, ground and trigger input of the oscilloscope are to be connected to the "Scope Out" connector AA on the SYM-1 board. The "Oscilloscope Output Driver Software" code provided in this chapter of the manual is to be entered into the SYM-1's memory and executed to enable the oscilloscope display. This code provides control of the oscilloscope display, as well as a rudimentary character set. Resistors R42 and R45 are to be adjusted to refine the displayed image.
Model: TE-8000
Battery: no
Adapter: AC 110 volt
Year: 1973
Chip: TMS0105
Info:TE8000 is a four-function desk calculator from 1973, built with a Texas Instruments single-chip processor.
The calculator is housed in a rectangular plastic box finished in imitation woodgrain.
The main circuit board and the display tube board are fastened to the base with a pair of light metal brackets. A 2-pin mains connector and the power transformer are mounted at the rear of the box, with the power switch attached to the moulded top cover. The transformer secondaries are hard-wired to the circuit board.
The display uses a set of miniature eight-segment vacuum fluorescent tubes, Futaba type DG10R1. (The small eighth segment at the centre right gives a "proper" numeral 4, but the processor only drives the usual seven segments). Eight tubes are used for the numerical display, and one (at the right) for polarity and error indication.
The keyboard is built as a single module and is attached to the main board via a cable and edge connector.
The TMS-0105 series single-chip processors contain all of the calculator circuitry with the exception of the power supplies and display drivers.
The rather untidy circuit board has a simple power supply at the rear and the TMS-0105 chip in the centre. The anode drivers for the nine tubes are at the left, with the eight segment drivers (seven plus decimal point) at the right. The keyboard attaches to the edge connector at the bottom.
Telegames Pong
In 1975, Atari started looking for ways to distribute their new home “Pong” system, but it wasn’t easy finding a distributor due to the track record that Magnavox had with the Odyssey. Retailers felt the price of the system was too expensive to draw an interest from the general public. After being rejected by numerous toys and electronics manufacturers Atari tried contacting Sears & Roebuck to see if they would have any better luck trying to work out a distribution agreement. They were directed to Tom Quinn who was the buyer for Sears’ sporting goods department, and he expressed interest but wanted the system demonstrated for a few executives first. Al Alcorn travelled to Chicago to demonstrate the pong home system prototype for the Sears executives and despite some minor technical issues with the prototype was able to obtain their approval.
Now that the executives gave their blessing, Quinn started to work with Nolan Bushnell to see if they could reach an agreement. Quinn wanted exclusive rights to the system as well as 150,000 systems before the holiday season. Bushnell agreed to the terms even though he knew that Atari would not be able to produce 150,000 units with their current facility. Atari acquired a new factory through funding by venture capitalist Don Valentine in order to produce the promised 150,000 units for Sears. In the end Atari was able to fulfill the order for Sears. All systems manufactured in 1975 were branded with Sears’ “Tele-Games” name but in 1976 Atari started releasing a version under their own brand name.
The success of home pong just like the video arcade version resulted in a multitude of clone pong consoles. Unlike the Magnavox Odyssey the home pong console and the clone consoles were only able to play one game “Pong”. Even with the limited ability of playing just one game the Pong systems became extremely popular and easily outsold the Odyssey.
Sears’ first venture into video games was very successful and they decided to continue the partnership with Atari expanding the tele-games brand by offering other video game systems with built in games. Atari continued to manufacture systems branding them with the Sears Tele-Games brand and by early 1977 many systems with built in games were released under both the Atari brand and the Sears Tele-Games brand.

1930 Texas Instruments was officially born as GSI (Geophysical Service Incorporated), which deals with geological surveys
for the oil industry
1951 GSI changes its name to Texas Instruments Incorporated.
1954 TI launches a real technological revolution by making the first silicon transistor, which it will soon make germanium is
obsolete, and starting the production of the first transistor radio, the Regency TR-1.
1955 TI creates the first infrared image sensor 1958 by Jack St. Clair Kilby, develops the first integrated circuit (chip), that is,
a series of passive and active electronic components that are different but connected in a circuit way, capable of fulfilling to a
specific function and made on a single semiconductor material platform, through a single manufacturing process.
The invention of the integrated circuit will be worth the Nobel Prize in Physics in Kilby in 2000. Also in 1958 TI made the
first analog-to-digital converter.
1964 TI is launching a new family of digital-logic devices (Series 7400) technology, TTL (Transistor-transistor logic),
the wide variety of logic functions offered by these devices available, the decree will become a worldwide success
standard adopted by most semiconductor companies.
1967 TI developed the first prototype of a pocket calculator. This is a project called Cal Tech and is represented by a
calculator integrated circuits capable of performing the four basic arithmetic operations with a precision of 12 decimal
places. The keyboard consists of 18 keys and the results of the calculations is displayed on a paper tape by a small
built-in thermal printer. The Cal Tech, however, is not the first pocket calculator business model as the first pocket
calculator, developed in collaboration with their IT, will be sold by Canon in 1970, the not insignificant price
of $ 400 for that period.
1972 TI enters the market with the TI-2500 Datamath model, the cost of only $ 150. The calculator used for the first
time a single chip to perform all math functions. The device is the ancestor of the modern microprocessor, the invention
of which is attributed to both the RT to Intel.
1975 TI enters the market with quartz digital watches.
1978 TI developed the first microprocessor for speech kicking off the first production of portable language translators,
and a line of teaching aids speakers including the "Speak & Spell," or "Il Grillo Parlante" and immortalized in the
famous film Steven Spielberg, ET.
1981 TI debut in the world of home computers with the model equipped with a TI 99 TI 16-bit microprocessor, the TMS9900.
The computer, equipped with a 13-inch monitor is designed to work with special boxes that contain magnetic memory
management programs, entertainment or educational software and comes with an interesting voice module that can be
used to reproduce stored documents. The market reaction to the launch of TI 99 is good but the initial price of the computer
($ 525) is still considered excessive. In the same year launched a major operation of commercial promotion and marketing
that includes the involvement of schools and universities. The number of users of the TI 99 is growing rapidly and will
grow the library of software available. Under the pressure of the increased sales volume and especially the increasingly
fierce competition, the TI reduces the price of the TI 99 and only $ 299 in April 1982 appears to be the leading producer of
home computer. In early 1983, TI will further reduce the price of his computer at $ 100 and sells its millionth copy
distribution network now includes more than 20,000 stores around the world and are more than 2000 software
packages developed.
1982 TI produced its first DSP (digital signal processor), a microprocessor from highly specialized functions that can run
fast times in digital signal processing.
1988 sees the light of the first device Digital Light Processing (DLP) projectors that will be used on commercial video
only from the early years of the twenty-first century.
In the mid-nineties the company alive, perhaps one of its most difficult moments. The cyclical nature of the semiconductor
market seems to increase and big moments of elation are racing moments of deep depression and instability. The company,
similar to what happens for various companies competing, he decided to quit the business sectors to greater volatility,
including that of personal computers, the military, that of DRAM and software and focus on those sectors where may have
and maintain a position of commercial and technological supremacy. Several production centers are closed or sold to
competitors and thousands of redundant employees worldwide. At this time the sale of Italian sites located in
Rieti and TI Avezzano and the closure of the Aversa.

1930 La Texas Instruments nasce ufficialmente come GSI (Geophysical Service Incorporated), la quale si occupa di
rilevazioni geologiche per l'industria petrolifera
1951 GSI cambia la denominazione e diventa Texas Instruments Incorporated.
1954 la TI lancia una vera e propria rivoluzione tecnologica realizzando il primo transistor al silicio, che renderà ben presto
obsoleto il germanio, e dando il via alla produzione della prima radio a transistor, la Regency TR-1.
1955 la TI realizza il primo sensore di immagini ad infrarossi
1958 per opera di Jack St. Clair Kilby, sviluppa il primo circuito integrato (chip), ovvero una serie di componenti elettronici
passivi ed attivi diversi ma connessi in modo circuitale, in grado di adempiere ad una specifica funzione e realizzati su una
unica piattaforma di materiale semiconduttore, mediante un unico processo di lavorazione.
L'invenzione del circuito integrato varrà a Kilby nel 2000 il premio Nobel per la fisica.
Sempre nel 1958 la TI realizza il primo convertitore analogico-digitale.
1964 la TI introduce sul mercato una nuova famiglia di dispositivi logico-digitale (serie 7400), in tecnologia
TTL (Transistor-transistor logic), l'ampia varietà di funzioni logiche disponibili offerte da questi dispositivi,
ne decretano il successo mondiale e diventerà uno standard adottato dalla maggior parte delle aziende di semiconduttori.
1967 La TI sviluppa il primo prototipo di una calcolatrice tascabile. Si tratta del progetto denominato Cal Tech ed
è rappresentato da una calcolatrice a circuiti integrati in grado di eseguire le 4 operazioni aritmetiche fondamentali
con una precisione di 12 cifre decimali. La tastiera è composta da 18 tasti e il risultato dei calcoli viene visualizzato
su un nastro cartaceo da una piccola stampante termica incorporata. La Cal Tech non rappresenta comunque la prima
calcolatrice tascabile commerciale in quanto il primo modello di pocket calculator, sviluppato in collaborazione
proprio con la TI, verrà messo in vendita dalla Canon nel 1970, al prezzo non trascurabile per quel periodo di
400 dollari.
1972 la TI entra nel mercato con il modello TI-2500 Datamath, del costo di soli 150 dollari. La calcolatrice impiega
per la prima volta un singolo chip per la esecuzione di tutte le funzioni matematiche. Il dispositivo costituisce il
progenitore del moderno microprocessore, l'invenzione del quale è attribuita sia alla TI che alla Intel.
1975 La Texas Instruments entra nel mercato mondiale con i primi orologi al Quarzo.
1978 TI sviluppa il primo microprocessore per la sintesi vocale dando il via alla produzione dei primi traduttori
linguistici portatili e di una linea di supporti didattici parlanti tra i quali lo “Speak & Spell”, o “ Il Grillo Parlante “
e immortalato nel celebre film di Steven Spielberg, E.T.
1981 TI esordisce nel mondo degli home computer con il modello TI 99 fornito di un microprocessore TI a 16 bit,
il TMS9900. Il computer, fornito di un monitor a 13 pollici è progettato per funzionare con speciali cassette di memoria
magnetica che contengono programmi di gestione, intrattenimento o di software didattico e viene fornito di un interessante
modulo vocale che può essere utilizzato per riprodurre documenti memorizzati.
La reazione del mercato al lancio del TI 99 è buona ma il prezzo iniziale del computer (525 dollari) è giudicato ancora
eccessivo. Nello stesso anno viene avviata una grossa operazione di promozione commerciale e di marketing che prevede
il coinvolgimento di scuole e università. Il numero di utilizzatori del TI 99 cresce velocemente e cresce di pari
passo la libreria delle applicazioni software disponibili. Sotto la spinta dell'aumentato volume di vendite e soprattutto della
concorrenza sempre più agguerrita, la TI riduce il prezzo del TI 99 a soli 299 dollari e nell'aprile del 1982 risulta essere la
principale produttrice di home computer. Agli inizi del 1983 la TI riduce ulteriormente il prezzo del suo computer a
100 dollari e vende il suo millionesimo esemplare, la rete di distribuzione prevede ormai più di 20.000 negozi sparsi in tutto
il mondo e sono più di 2000 i pacchetti software sviluppati.
1982 la TI produce il suo primo dispositivo DSP (Digital signal processor), un microprocessore dalle funzioni estremamente
specializzate in grado di eseguire in tempi velocissimi elaborazioni di segnali digitali.
1988 vede la luce il primo dispositivo Digital Light Processing (DLP) che verrà impiegato su proiettori video commerciali
solo a partire dai primi anni del XXI secolo.
A metà degli anni novanta la compagnia vive forse uno dei suoi momenti più difficili. L'andamento ciclico del mercato dei
semiconduttori sembra accentuarsi e a momenti di grossa euforia si succedono rapidamente momenti di profonda
depressione e instabilità. L'azienda, analogamente a quanto accade per diverse compagnie concorrenti, decide di uscire
dai settori commerciali a maggiore volatilità, tra i quali quello dei personal computer, quello militare, quello del software e
delle memorie DRAM e di concentrarsi su quei settori strategici nei quali può vantare e mantenere una posizione di
supremazia commerciale e tecnologica.
Numerosi centri di produzione vengono chiusi o venduti alla concorrenza e migliaia di dipendenti licenziati in tutto il mondo.
Risale a questo periodo la vendita dei siti italiani TI localizzati a Rieti ed Avezzano e la chiusura del sito di Aversa.

It is obvious that the model professional - manufactured for Koh-I-Noor Hardtmuth - is a hybrid of three different products:
| • The basic functionality is borrowed without any doubts from the TI-30 introduced in 1976 • The double-shot injection molded keys are known from the Business Analyst-I • The yellow-brown keyboard plate is... unique |
Dismantling this model professional manufactured in 1978 reveals a standard TI-30 printed circuit board (PCB) with the well-known TMS0981 single-chip calculator circuit.

Info: If you take your time comparing this calculator with all other members of the second slanted series (BA-54, TI-57-II) you notice something very special. The keyboard position doesn't fit to the usual spacing. The ON/C-key is misplaced and one key is super-sized. You have to open the calculator to get the answer: This is not the usual construction of a slanted calculator! A very small printed-circuit-board, actual the form factor of a modern slimline calculator like the BA-II, is fitted into the housing.

Allow me to introduce myself. I'm Fabrizio, and together with other friends we take care of the museum dedicated to Texas Instruments. This voluntary organization was created to preserve, document and share the technology of all the objects that have made the history of Texas Instruments and beyond (for example Apple and HP ), the final goal is the birth of a museum in the city of Rieti (Italy), where in the 1970s he built one of the most important factories in Italy and Europe.
Much of the technology we enjoy today, such as personal computers, smartphones, tablets, gaming systems, and myriad other devices equipped with a microprocessor “brain,” has its genesis in technologies developed as a result of tenacious experimentation.
We have been passionate about all types of technology since we were children, we try to arouse everyone's curiosity but especially boys and girls from generations younger than ours, we are promoters of many initiatives, including cultural ones, such as conferences, but above all participation in exhibitions, fairs, meetings with students in schools and museums by making our Texas Instruments material available.
This museum is always looking for watches, calculators, games, computers of historical interest. If you own one of these items made primarily in the 20th century, the museum may be interested.
If you have something that seems to match these interests and are looking for a new home, please contact us with information about your item, which you would like to donate or sell.

Info:Texas Instruments took in 1976 in conjunction with mathematics educators at two major universities an initiative to introduce a group of 6 calculators for educational use. Including the Little Professor, the limited function ABLE calculator, the colorful TI-1205 and TI-1255, the TI-30 and the sophisticated SR-51-II, these calculators helped students understand and use math concepts from kindergarten through college and career.The TI-1205 is based on the TI-1200 but includes rechargeable NiCd-batteries instead the standard 9V block battery. To enhance the readability of the keyboard both the size of the numerals and the color-scheme was improved.Disassembling the TI-1205 with Date code 1977 LTA and manufactured in May 1977 in Lubbock, Texas reveals an internal construction identical with the TI-1255. Instead of the 9V battery found in the original TI-1200/TI-1250 design, the TI-1205 makes use of 2 rechargeable, AA-sized NiCd (Nickel Cadmium) batteries. The printed circuit board (PCB) of the TI-1205 adds both the charging circuit for the batteries and a step-up converter to generate the 9V supply of the TMS0972 single-chip calculating circuit to the design known from the TI-1250.

Info:The TI-1757 II "Melody Calculator" added to the similar TI-1755 the capabilities to play own melodies or the "Happy Birthday..." rhyme. The music function gives 10 notes of a scale. With 2 notes below the octave and one above you can play simple tunes. Another key allows you to play either flat (b) or sharp (#). This transforms the basic key of C to F and G by flattening the B to Bb in the first case and sharpening the F to F# in the second case. Thus most tunes can be played with a little practice.
