Fix this!!!  If those pins are touching, then the SCSI card is set to
two SCSI IDs simultaneously, which may prevent it from working.  (I
don't know what effect it will have.)

Unbend those pins.  The card should be set to SCSI ID 7, which is the
pair furthest from the edge of the card.

System 4 uses the firmware on the card, while System 5 and later use
the SCSI Manager, which could use a different method to identify
devices on the bus.
