I tried margining the power supply, still fails self test.  The board 
originally powered up
fine with nothing connected to either the SCSI or drive end.  So, I went 
back to
that condition, and it still didn't pass self-test, which leaves it dead.

It has nothing to do with SCSI termination.

What I am looking for is a SCSI - formatted Pertec interface.  The 
formatted Pertec interface
is two 50-conductor ribbon cables.  I have a good Adaptec SCSI PCI card 
with all possible
SCSI flavors on it.  Your boards don't sound like it has anything to do 
with Pertec tape.

Another option is a USB - formatted Pertec or a PCI card, but I have not 
found that
anything like that exists.  I have found some ISA cards that were made, 
but really don't
have much ISA motherboards available, and of course none that would run 
Linux.

Thanks,

Jon
