A couple of interesting items followed me home recently - a Digiac Model 5502 Monochrome
Monitor Exerciser and a Digiac Model 5503 Dot Matrix Printer Exerciser. The 5502 seems
complete. The 5503 is missing the (presumed) DB-25 and Centronics cables, but I can
replace those using old printer cables on hand.
In addition to the models that I own I have also seen references online to a Model 5501
Power Supply Test Load Unit and a Model 5504 Floppy Disk Drive Exerciser.
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?

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.

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.

Mark -
My 5502 and 5503 were given to an employee of the company that owned them some years after
that company stopped using monochrome monitors and dot-matrix printers. They sat on a
shelf in his garage for many years and got pretty dirty. I will try to find some time this
weekend to clean them up and photograph them. Whether I get to it this weekend depends
upon whether I can finish up some paying work that is queued up in the shop.
