I received a qbus board with a small pdp11/23 system recently, and I can't find any
info about it with my best googling.
It's made by data systems design, copyright 1980, appears to be model 804120-01.
Dual-width qbus board, with a 34-pin ribbon cable connector on the top board edge, maybe
floppy controller?
The only real non-ttl non-rom chip is a AM2901BPC. This seems to be a four-bit bit slice
micro...
Anyone ever seen this beastie?
Thanks.
