G10 SCSI I/O signal. In SE mode, the
G9 SIO− pin is the SE signal pin, and the
SIO+ pin should be connected as a
virtual ground on the SCSI
connector.
F12 SCSI REQ signal. In SE mode, the
F13 SREQ− pin is the SE signal pin, and
the SREQ+ pin should be connected
as a virtual ground on the SCSI
connector.
F10 SCSI C/D signal. In SE mode, the
F9 SCD− pin is the SE signal pin, and
the SCD+ pin should be connected
as a virtual ground on the SCSI
connector.
E13 SCSI SEL signal. In SE mode, the
E12 SSEL− pin is the SE signal pin, and
the SSEL+ pin should be connected
as a virtual ground on the SCSI
connector.
E11 SCSI MSG signal. In SE mode, the
F8 SMSG− pin is the SE signal pin, and
the SMSG+ pin should be connected
as a virtual ground on the SCSI
connector.
D13 SCSI RST signal. In SE mode, the
D12 SRST− pin is the SE signal pin, and
the SRST+ pin should be connected
as a virtual ground on the SCSI
connector.
C13 SCSI ACK signal. In SE mode, the
D11 SACK− pin is the SE signal pin, and
the SACK+ pin should be connected
as a virtual ground on the SCSI
connector.
C12 SCSI BSY signal. In SE mode, the
D10 SBSY− pin is the SE signal pin, and
the SBSY+ pin should be connected
as a virtual ground on the SCSI
connector.
