Hey all --
I picked up an oddball calculator/computer -- it's labeled on the bottom
as a Sharp CS-4801 "Electronic Calculating Machine." At first glance,
it looks like a standard desktop 4-function printing + stat function /
memory calculator, but it also has a small QWERTY keyboard that slides
out from the front. The display is a 20-character alphanumeric VFD.
Opening it up reveals a Z80 CPU, 32K of RAM and an EPROM, so there's
clearly more than meets the eye here. Unfortunately, I can't get the
machine to do anything other than normal calculator functions. I
haven't yet dumped the EPROM, but I plan to later this weekend.
Anyone know anything about this series?
Thanks,
Josh
