It sounds like a device for testing IBM terminals and/or controllers for
IBM 8100's and/or mainframes.
It may support two different connection types. SDLC (probably a standard
25-pin D Connector) and a thingy called an 8100 Loop (for the 8775
terminal) which is a local/remote ring protocol that predates Token Ring.
Don't discard it or destroy it -- they are probably not all that easy to
get, and I can imagine that one or more folks on this list might be
interested in it.

I went computer scrounging today and found a brief case style tool box
with some
kind on IBM tester in it. I have so idea what it is but it has
an 8" floppy disk drive in it! I got the floppy disk too. It has a NICE
handset with a 4 line LED display and a full keyboard attached by a cable.
There's also a lot of strange looking connectors and adapters with it. The
main box has an "IPL" button and three connectors labeled "PIO",
"S LOOP"
and "R LOOP". The quick reference chart only calls it a "MD".
There's a
tag on it that says "TYPE 910x 002". Anyone know what it is and what it's
for?

I powered up the THING today. It says it's a Stand Alone Terminal
Exorciser, PN 08309930, date 01/84. It passes the self test and brings up a
menu that lets you select 327X Tutorial, 327X BSC, SDLC/SNA or R-LOOP.
Selecting the R-LOOP option brings up another menu for 8775 Device or 3276
Device. That's as far as I can get in the menu, after that it asks for a CU
address or will autoscan for it but of course there's nothing connected so
it doesn't find what ever it's looking for. Does anyone know any more
about it?
