Basically it's a 4000-series CMOS counter and some drivers. IIRC, you had to provide VPP and probably the other voltages. I think it's limited to 2708's. It's in my hellbox and I'm not even sure if I have the docs for it--although I just might be convinced to check for them if someone wants to make an offer on it. It's never been used--the fellow with the KIM-1 who was having me build a little PS for this thing lost interest when he figured out he'd have to also buy a UV EPROM eraser (not cheap back then).
