  I have a TI-99/4. The keyboard is so terrible the computer is nearly unusable. It's much worse than the keyboards that usually make the "bad keyboards" list - I'd happily spend all day typing on an Atari 400 or an IBM PCjr. It makes the Timex Sinclair feel like some expensive Cherry MX board.

    The 4A's keyboard is much better.

      It really is! Especially the black ones. They used a few different manufacturers, but all the ones I have feel pretty good.
