    The big irony, the TI-99/4 was the first 16-bit PC on the market, competing with Apple ][, Atari 8-bit, Commodore, etc., and should have significantly outrun them. BUT, TI squandered this advantage, the TI-99/4 and TI-99/4a only have 256 bytes of RAM hooked up to the CPU, with all other RAM (16KB standard) running through the video display controller — this made the TI *slower* than the 8-bit competitors.

    TI did that so the 99/4 would not compete with their line of Mini-computers based on the TMS9900. Really dumb but a very common one. DEC could have come out with a PDP-11 based PC that could have been cheaper than the IBM PC and with a large software base before the PC even showed up same with TI but they didn’t want to cannibalize their mini computer market.
    That is also the reason that IBM didn’t make the PC that used an IBM 360 based CPU maybe one based on the model 22 or 40 or 50.
