This section summarizes pinouts for the single-ended high-density SCSI (68-pin).
Figure A-1 shows the 68-pin connector.
In Table A-5, the hyphen preceding a signal name indicates that the signal is active-low. Eight-bit devices that connect to the P cable leave these signals open: -DB(8), -DB(9), -DB(10), -DB(11), +DB(12), +DB(13), +DB(14), +DB(15), +DB(P1).
All other signals are connected as shown in Table A-5.
