Welcome to my Texas Instruments collection.
This page is a repository for all of the Texas Instruments systems, peripherals, and accessories in my collection – it’s currently a work-in-progress, and I’ll continue to add things as and when I have the time.
Texas Instruments TI-99/4A
|Release date||June 1981|
|Operating system||TI BASIC v1.0|
|CPU||TMS9900 @ 3 MHz|
|Memory||16 KB (+256 B)|
The TI-99/4A was released in June 1981, to address some of the issues with its predecessor, the TI-99/4. It added a full-travel keyboard, improved graphics, and a unique expansion system, which supported peripherals including a speech synthesizer. At half the price of the original model, sales picked up significantly, however TI’s insistence on limiting publishers continued to starve the platform of software.
