Notes:
[1] PCB part number label here
[2] "NC" models do not have connector J5, and have a single 80 pin combined SCSI I/O and DC power connectorr
instead of the normal 50 pin SCSI I/O and 4 pin DC power connectors. Included among the 80 pins are the SCSI
ID, Motor Start and Delayed Motor Start select functions, and the synchronous spindle master sync signal and
the remote LED signals. Do not use J2 and J6 for these five functions if the host uses the ones included in the 80
pin connector. See Table 11.6.3-1c for a list of pin numbers vs. signals for the 80 pin connector.
