The model is Compact Computer 40, abbreviated as CC40. It's a small 9 X 5.5 " unit, gray, with a full keyboard including numeric keypad, and a one-line 30-character display. It has 8k RAM and 2k ROM (I think) and BASIC and a monitor in ROM. A cartridge port, HEXBUS port for plugging in cool stuff which I don't have (like a tape drive), and AC adapter port. Runs on 4 AA batteries. Has lots of math functions as well. Comes with a manual, mostly about BASIC, and anothe r book called 'Learn BASIC: A guide to programming the TI CC40' It's made in 1983. There is an ad for it that runs '20 pages of notes, a thesis, algebraic formulas. Can you make a date at eight? Turn to your TI Compact Computer. By 7:14 your TI CC40(tm) has your notes filed, the changes made in your thesis, and all those formulas worked. The CC-40 goes where you go -- the classroom, library, anywhere. It's cordless, compact, sophisticated. It gives you much of the problem solving power of Apple or IBM personal computers. But it's a fraction of the size and price..." the ad goes on to say 6K RAM, 34K ROM, which doesn't agree with my manual. This thing runs at 2.5 Mhz,BTW. So, if anyone has any cartridges or accessories (that tape drive sure looks nice!) that they would be willing to sell/trade/give to me... ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
