Texas Instruments TI-99/4A

My TI-99/4A (added to my collection in 2015)

Technically a 16-bit CPU, but I am still leaving this in the 8-bit category, it’s of the era, and capabilities of other 8-bit micros.

  • TMS9900 CPU at 3Mhz
  • 16Kb RAM (on 8-bit bus)
  • TMS9918A VDP/Graphics with hardware sprites.
