What are pinouts for Macintosh Plus SCSI Connector?
ANSWER From: Gary Field (garyf@wang.com) Note that this connector is NOT COMPLIANT WITH ANY SCSI STANDARD! The grounding is insufficient and does not allow for proper twisted-pair transmission line implementation. It is recommended that a short adapter cable be used to convert to the more common Centronics style 50 pin connection rather than extend the 25 pin connection any further than necessary. The Macintosh Plus used a NCR 5380 SCSI chip controlled by the MC68000 processor.
