50pin f lat SCSI cable
Internal SCSI Connection
68pin f lat SCSI cable
Note: The 50 pin SCSI is a n 8 bit SCSI bus, the 68 pin SCSI is a 16 bit SCSI bus
which ha s a pin-to- pin connected to the 50 pins SCSI connector.
Note: The SCSI termination must be on for the both side. The beginer and end
must set the terminator on - otherwise the SCSI bus will not operate properly.
For linking both the 50 & 68 pin SCSI together, the High byte terminator must
set to on and Low byte set to off.
