AT&T XPC Tutor?

One of the very few goodies (I rarely partake in the stuff that comes
through the VCF, preferring the attendees to get the good scores, if they
can get to it before Hans) I ended up with from the VCF (thanks, Stan!)
is an AT&T "XPC Tutor". It's basically a microprocessor trainer of some
sort, circa 1986. The main CPU(?) inside is a very odd chip labeled

M T7102-NC
11 86 77

I thought at first this must be a Hobbit chip but it's too early (assuming
"11 86" is the date code, which would seem likely based on the date codes
of all the other ICs) and nothing comes back from Google.

Does anyone have any idea what this might be?

The other interesting thing about this trainer is that it has a 6809 in
the middle of the PCB, and it has 6 serial ports (or at least 6 DB25
connectors with several wignal lines each) poking out the back.

I'll post a picture if it'll help jog a memory.
