Advanced Digital Corp. -- Super Quad SBC
Advanced Digital Corp's first
S-100 board. It was a very densely packed Z80 (4MHZ) based SBC.
This board was IEEE-696 compatible and had 64K of dynamic RAM on board.
This memory could be banked selected or extended addressing. There was a
Western Digital FDC chip capable of talking to both 8" and 5" drives.
There were two serial ports (Zilog SIO) and two parallel ports (Zilog PIO).
There also was room on board for up to 4K of EPROM. ADC provided
drivers for CPM, MP/M and Turbo-DOS. The board was meant to primarily serve
the ADC Super-Slave
boards in a multi-user system, but of course it could be run in any S-100
system by itself.
