I believe the MiniExchange used to run $795 (or maybe $695).
It's really more than an ABCDEFG switch because any two devices on it
can connect themselves together (if they "know how")... so I guess that
makes it more like an ABCD-ABCD crossover switch! :-)
But the device is something of a PITA.  Not fully reliable, and "knowing
how to talk to it" requires that the device that wants to, be able to assert/d
Data Terminal Ready whenever it wants to change its "connection".  And it
has some undocumented programming gotchas (e.g. if two devices both request
"switching attention" at close to the same time, one of them is flat-out
ignored).
Still, if I knew where to pick another one up for $40, I'd probably do
it!

The DECwriter III also has spools behind the platen.
Why don't you check the serial/model-number sticker (silver, probably
on the back or bottom of the unit) and see what it says?  My handbook says
that a DECprinter III is a keyboardless DECwriter III, a/k/a LA120 (which
was made in both keyboard-equipped and keyboardless models).  But it might
also be an L*S*120, which was made for several months before the LA120 was
introduced.
Then... what did you want to know about it??
Sorry, but I've forgotten.

All of the LA120/LS120/LA180, and even the LA36, models match that physical
description.

If you truly have a 100A, the best advice I can give you is to sell it for
whatever you can get and buy a 100+, which can be had now for around $300.

Short of that, you might try a CP/M based comm program, such as Kermit.

The rationale for the above advice is that the 100A interrupt structure
conflicts with that of MS-DOS, and that may be causing your problem.
