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
