Texas Instruments TI-99/4a Computers

The TI-99 computers from Texas Instruments are a terrific and affordable vintage computer to start collecting. It seems like almost all the games were pretty good.

I have been collecting vintage computers (Apple, Atari, & Commodore) for about a decade now and just added a Texas Instruments TI-99/4a to my collection. I never saw one of these computers before now. Perhaps they were not sold in my area. But it is a really cool little computer considering it is almost 35 years old. I would have been really happy to have owned a TI-99 way back then.
