[net.micro.cpm] Zerox 820-II

jdhill@bbnccc.ARPA (Jack D. Hill) (05/16/86)

Does anyone out there have schematics for the Zerox 820-II? I have schematics
for the 820-I but there are too many differances in the disk interface. Right
now I have a 5 1/4" and an 8" drive connected to it but I would like to add a third.
In the meantime can anyone tell me if there is a drive select 3 or 4? If so
what are the pin outs?
Thanks,
Jack
