Does anyone have any spare WD-1000, WD-1001, or related disk controllers,
or documentation on them?
These are *not* ISA bus cards, they have a parallel interface to a host,
and control up to four 5.25-inch Winchester disk drives using the ST-506
or ST-412 interface. (Some models supported older 8-inch drives as well).
They use the Signetics 8X300 or 8X305 processor, WD-1100 series support
chips, and firmware in bipolar PROMs.
Thanks,
Eric
