In addition to the models that I own I have also seen

Drive Exerciser.
I have one of the 5504 disk drive exercisers. I don't have any documentation for it
yet. It includes a cable which is connected to a bank of switches under a locking cover,
apparently for simulating some sort of fault conditions. I don't know what the cable
plugs in to, though. The exerciser does seem to work, though its switches are bouncy.
I have no manuals - does anyone on the list have scans
of any of the manuals for the Digiac 55nn series that they would care to share?
If any manuals turn up for the 5504, I'd sure like a copy! I should take some pictures
of it when I get around to it. It looks kinda pretty with all of its nice color-coded
buttons. I would also enjoy seeing pictures of the other 55nn series exercisers.
