IBM thingy!

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.
