TI 99/4a

Although The Texas Instruments TI 99/4a was a contemporary of the Apple ][, Atari 800 and much of the Radio Shack line it wasn't nearly as successful as those computers. One reason may have been its price, which was initially far higher then its competitors, when compared as equally capable systems.

The boxed, as new, Texas Instruments 99/4a

I have two TIs in my collection. One is a nearly brand new, almost never used unit with its original box and documentation. The other is in less pristine shape but came with a TI expansion unit with with a floppy drive.

The later TI and expansion unit was donated by Pete Hansen.
