Yep - the NEC uPD7210C is (as far as NEC are concerned) an "Intelligent GPIB
Interface Controller". I've since found out that SMC (Standard Microsystems)
second-sourced it as the COM 7210 - I've been working from the SMC datasheet,
which isn't too bad.
What I would like to do is get hold of a few 7210s to play around with. A
GPIB-controlled power supply would be rather neat - that or a Gameboy Camera
hooked up to the GPIB. I think I've still got some Fairchild 96LS488 GPIB
controller chips lying around somewhere, but I'll be damned if I can find a
datasheet for them anywhere.
Cue the inevitable bunch of people accusing me of being lazy for thinking
about using a GPIB chip instead of bitbanging GPIB in software...
Later.
