Oh, ye of little faith. The guy from the future who
was looking for the
5100 took one of those back in time to around 1066.
Why do people always forget the HP9830? It was 2 years before the
IBM5100, and while HP called it a calculator, it was a full-blown desktop
computer with up to 16K bytes of RAM running BASIC from ROM.
OK, it had a 1-line alphanumeric LED display, not the CRT that the
IBM5100 used, but I don't think that's enough reason to forget it :-)
(SOrry, I'm biased. I love the HP 98x0 machines...)
