TI PC

Model: Professional Computer (PC) Color Version Adapter: 110 volt or 220 volt (Italy) Year: 1983 Keyboard: QWERTY full-stroke keyboard with arrow keys and separated numeric keypadCpu: Intel 8086 Speed: 5 mhz CO-processor: 8087 Ram: 64k (up to 768k) Sound: Beeper Text mode: 80 x 25 Graphics mode: 720 x 300 Size - Weight: 47 x 42 x 19 cm / 12 kg with monochrome monitor / 14 kg with the color monitor I/O ports: Parallel/Centronics port, 5 expansion slots (non IBM compatible), 4 x serial ports Media: two 5''1/4 disk-drive (320k) OS: MS-DOS 2.1 CP/M 86, UCSD P-system, Prologue and Concurrent CP/M 86. Peripherals: 10Mb or 20Mb hard-drive ( need interface), RAM expansion cards, Voice recognition card, Ethernet card. Price: 64k model about 3000$ (USA, november 1983) / 64k model : £ 4.000.000 (Italy, 1985) Info:The TIPC is very similar to the IBM PC both architecturally and from a user-experience perspective, with some technically superior aspects.It is based on the Intel 8088 CPU and an optional Intel 8087 floating point coprocessor. It supports MS-DOS compatible operating systems,but is not a fully IBM PCcompatible computer. Alternative operating systems are CP/M-86, Concurrent CP/M-86, and the UCSD p-System. The TIPC was reviewed in Byte magazine in its December 1983 issue. The CPU clocked at 5 MHz (a bit faster than the 4.77 MHz of the IBM PC) and has 64 KB of RAM pre-installed. A RAM board can be installed in an expansion slot providing an additional 192 KB or RAM, for a maximum of 256 KB. A later version supports up to 768 KB of total memory. The computer featured 5 expansion slots and has either a 12-inch green-phosphor monochrome (CRT) monitor or a 12-inch color monitor with a color graphics resolution of 720x300 pixels. For text, the display shows 25 lines of 80 columns each. The device has a 5¼-inch floppy disk drive and can support a second floppy drive or a "Winchester" hard drive without requiring the use of an expansion slot or separate chassis, and typically features one of each.

Troubleshooting

For this TIPC we used a Seagate ST225 (20 mByte) to be formatted with option 4 (miniscribe 3425). One thing that takes you back in time is the wship.com command from DOS 2.13 that allows you to park the HD heads.

As for the floppy we used this 360 kByte y53, as we have to repair the original one.

Model: Color Graphics Video Controller assy:2232435-000

Info: For monochromatic operation, only the monochromatic card is used; to have the color function it is necessary to insert the color card sandwiched on the monochromatic card.
