implementation.
A11 SCSI ATN signal. In SE mode, the
C10 SATN− pin is the SE signal pin, and
the SATN+ pin should be connected
as a virtual ground on the SCSI
connector.
B10 SCSI low data byte parity signal. In
D9 SE mode, the SDP0− pin is the SE
signal pin, and the SDP0+ pin should
be connected as a virtual ground on
the SCSI connector.
C9, B9, SCSI low data byte signals. In SE
A9, D8, mode, the SDx− pin is the SE signal
C8, B8, pin, and the SDx+ pin should be
A8, E8, connected as a virtual ground on the
B7, A7, SCSI connector.
