Welcome. In 1981, Texas Instruments, Inc. released a modified and much improved version of its previous 99/4 Home Computer. It was named the Texas Instruments TI-99/4A. It was a modular computer system, meaning that it could be expanded to serve the users' needs by purchasing as little or as many add-ons as desired. It offered the typical home user a computer system that was easy to use, easy to expand, and enjoyable to own. Several other computers were designed by Texas Instruments, Inc. following the TI-99/4A. However, for the most part, they stayed in the prototype stages of production. In 1983, Texas Instruments decided to leave the computer manufacturing business citing unacceptable profit loss. This was due to T.I.'s reluctance to share its patented designs with third-party manufacturers who could have produced products for use with the T.I. computers - products that users of most other computer systems had available to themselves already.

It is this web site's purpose to serve as an ever-expanding source of useful information to help users of Texas Instruments Computers keep their machines running and to help users get the most use and the most pleasure from them. I personally have a very large collection of Texas Instruments TI-99/4 and TI-99/4A equipment, including 3 consoles (one a mint condition, unused 99/4), peripheral expansion system with RS-232 card, TI-99/4 printer, 2 disk memory drives, over 45 program modules, etc., etc. So, if you need help with issues regarding your system, I will be providing my e-mail address below. Perhaps I can be of help - you never know.

Web Master,

I have been interested in programming computers since 1982, when I first programmed an Apple II+. I was 13 years old. I am now 34.
