Texas Instruments TI99/4A

Texas Instruments could use their own chips and experiences for the

development of the TI99/4a. Therefore they didn't use a 6502 or Z80

as a main CPU. The computer had a bit success in the U.S.A. but wasn't

very popular in the U.K. or Germany.

One curiosity: There was a PC-box for the TI 99/4a - a complete PC

which could be connected to the TI. The only thing the TI got do

for the PC were the keyboard inputs.
