It is a DS1287
The issue is finding out what the contents should be, since it isn't
documented in the surviving manuals.
Some of this was figured out in getting the 2030 to run in MAME and there
is a guess at the correct contents as a rom image there.
If you have the original timekeeper part, the unique part of the
machine's ethernet address is written on a label on top of the part.
