TI 1205Model: TI-1205
Battery: 2 x AA ni-cd
Adapter: AC9130
Year: 1977
Chip: TMS0972
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:
In 1981/1982 Texas Instruments introduced not only cheap looking calculators manufactured in Taiwan like the TI-1015 or TI-1006 but some very stylish and thin calculators. The line covers the TI-1754 (credit card sized), TI-1755 (golden trim), TI-1756 (silver edition of the TI-1755) and TI-1757 (Music Card). All four models got an audible instead of a tactile feedback of the entries.

TI 1755Model: TI-1757 II
Battery: 2 x LR54
Adapter: 
Year: 1983
Chip:  Sharp LI3033MT
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.
