Texas Instruments TI99/4A Clones

August 31, 2023

Based in the UK, the Texas Instrument TI99/4A is not a computer I had seen much of when it was introduced in the early late 1970’s and early 1980’s. It its purported to be the first 16-bit home computer and we would not see any 16-bit machines until the Commodore Amiga and Atari ST in the mid 80’s and maybe the Sinclair QL if you consider its cut-down MC68000, MC68008 a 16-bit machine internally.

So I found some technical websites that have some information on how to make you very own TI99/4A clone:
