We have a Vintage Texas Instruments TI-99/4A computer with software cartridge and original paperwork which includes the manual. I have the original packing but not the box. I cannot test it because I do not have the power supply.
The Texas Instruments TI-99/4A is a home computer, released June 1981 in the United States at a price of $525 ($1,366 adjusted for inflation). It's an enhanced version of the less successful TI-99/4 model, which was released in late 1979 at a price of $1,150 ($3,749 adjusted for inflation). The TI-99/4 had a calculator-style chiclet keyboard and a character set that lacked lowercase text. The TI-99/4A added an additional graphics mode, "lowercase" characters consisting of small capitals, and a full-travel keyboard. Both used 16-bit processors, making the TI-99/4 series the first 16-bit home computers.
It looks new. Selling the computer the software called Personal Record Keeping, all the manuals and paperwork I have for it, and foam cover for the PC. Asking $25 for everything.
