There are two SCSI controllers on the 735.  The F/W connector requires
differential drives which may be why the machine doesn't see your drive.
The single-ended controller connector is an HD-50.  On my 735, there is
a short jumper from the CPU module to the module for the internal hard
drive.  The two HD-50 connectors on the left (top) connect to each other
and the internal hard drive.  They don't need to be used if you are using
all external drives.
