Thinking about
it, Whitechapel's MG-1 had SCSI on the main PCB as standard
equipment, and that was in 1984, so a couple of years before the Mac Plus.
Does
it? I've jeust been through the schematics and I can't find any SCSI
inerface. The hard disk interface is essentially ST412, but there's a
connector allowing acces to the HDC chip pins which was going to be used
for an SMD interface. Problem was, the DMA controller couldn;'t handle
SMD data rates...
I think the Hitechs had SCSI on the motherboard (which didn't contain the
CPU, that was a plug-in card), but they're considerably later.
