I bought an S-100 card today at a hamfest for $1.00, now can someone tell me what it is ?
It's a "65k byte SupeRam 2" P65D2 Rev. C by PIICEON, Inc.
It has 64k of DRAM on it, 4 rows of 8 4116's, but the rest of the board does not look
very "Ram-like", AND it has a 34-pin board edge connector at the top of the
board. I realize that this suggests a 5" floppy drive interface, but a combined RAM
and FDC card ????? Plus, the edge connector is VERY un-floppy like, normally a floppy
connector would have half of the pins being ground, this clearly looks like it has active
signals on almost all 34 lines.
Anyone who has information, it would be appreciated. I'd most like to get a manual
and switch settings [there are FOUR dip switches on this thing], also the IC at 9B is
missing and the board screening does not identify what should go there.
Regards,
