My TI-99/4a

February 14, 2022

The Texas-Instruments TI-99/4a was also one of the very first computers I used. Did not have a tape lead for that machine, so did not use it very often as I lost everything everytime I powered it off. But did some programming with it.

Re-acquired the TI-99/4a two years ago.
