I finally heard back from the gentleman who responds to requests from the
e-mail address at Basicon's former site... he sent me scans of some paper
docs... JPGs, but quite legible. It fits the final pieces of the puzzle
together for me, including fixing an ambiguity I had with one of the
power/comms connector pins, and giving programming examples for talking
to the MM58154A clock/calendar chip.
If you ever happen to run across a 3"x4" board with an INS8073 and an 8255,
embedded in something, nab it - it's a cool little piece of the early 1980s.
Thanks to all for your input and help figuring this thing out.
