<Now I know that many people didn't consider it a reasonable computer, but
<the TMS-9900 did make a memorable appearance in the TI-99/4/4A of blessed
<memory - 16K if I recall correctly. Once you added a PEB, RS-232 card, 32
<memory card, 2 HH DS/SD floppies and an Extended Basic cartidge, it was a
<fine computer.

Not quite true. There were the TI business systems, the ti990-xxx boards
that could be systems or used as SBCs and after the TI99/4a there was the
Geneve system that was marketed. Another was a ti9900 board for S100.
Also Technico systems had both the basic Super starter system as a SBC
and expansion boards for it as well.

It didn't make the impact because TI didn't market it like intel, moto or
Mos tech.. Actually they didn't market it at all until the were an also
ran. Shame too as it was the fist 16bit single chip and vastly better than
8086 considering it was 4 years earlier.
