However, the termination is something that I've
been concerned with.
Howard used it with a short (~3ft) SCSI cable. I'm using it with a longer
(~6ft) cable. The tape drive has two 50-pin IDC connectors on the back.
There's a ribbon cable coming out of one of the connectors with two
amphenol connectors on the end. One amphenol connector is terminated, and
the other is connected to my SCSI cable, which is then connected to my
SCSI interface on the PC. The other 50-pin IDC connector is just open. I
mentioned to Howard that this didn't look right but he said it always
worked for him.
I have (or at least I think I have) a terminator that will plug into a
50-pin IDC type connector, but I can't find it. I'm hoping that fixing
this cabling mess will solve the problem.
Ah, termination. I never believed it was right until I took apart
every device and confirmed the wiring. I've seen commercial external
SCSI boxes wired the wrong way inside (making illegal 'T's instead
of daisy-chain), making proper termination impossible. Good cables
can make a difference. Your 6-foot versus Howard's 3-foot could
make a difference. Try swapping cables.
I'll try again, though at this point I'd rather
be shot in the head.
Obviously it's not going to work without the SCSI blood sacrifice.
