Ah, but it's not that easy.  The only way I know of to hook a standard SCSI
interface board to an ST via the DMA port is to buy the Berkeley Micro
Systems' hard disk interface board.  This is a board which, when hooked to
the ST DMA port, gives subset of the SCSI standard port.  One can hook a
SCSI hard drive to this port, or can go further by then hooking a
SCSI-to-ST506/ST412 interface.  This would allow hookup of IBM-PC style
hard drives.

While we're on the subject of drives, just WHO has gotten a 5.25" drive
working on the ST?  Would anyone like to mail me the pinouts to make a
cable and the modifications required to the mechanism?  I don't want to
hook it up inside an ST drive, I'd like to plug it in to the back of one.
