I tried my much older ISA Adaptec AVA-1505 SCSI card and everything
worked great.
I'm a little disappointed by the fact that it isn't working with the
Buslogic card, however your reasoning behind needing an active
terminator makes sense. I'm going to see if I can find one and test it
out again.
Do you think the terminator is most likely the problem, or should I
start looking for a better SCSI card?
Thanks for all your help. Its incredible that we were able to solve the
problem within 20 hours!!!
