OK, per page 13-31 of the CE Handbook, that would be the 79xx disc loader
ROM. It's possible that the white stick-on HP label fell off at some
point, and the owner wrote the part number on the chip in pencil. If
you're curious, you can check the ROM contents against the loader listing
on page 13-18 of the Handbook (when you get a base set board, that is :-).
Top priority would be to obtain that base set microcode board. You really
can't get anywhere without it.
