       ^^^^^^^^^^^^^

Here goes nothing:  my own "internal" 105S came with terminating
resistors.  Look for SIP's on the PC board just above the SCSI
connector.  Try wiring one drive at an unterminated end of the bus.

As long as I'm here, should I even *think* of removing the drive's
terminating resistors?  I hate to fix something that ain't broke,
but I'd like to do things right.  Tom will have to do something
(maybe).  Is trading-in the drives his only option?
