A friend who currently runs an PDP11 as part of his business had a failure of one of the
PROMs in his disk/tape controller. These beasts seem to be unobtainium - does anyone have
any spares in their kit or know of a source. Understand that the chips are
one-time-programmable so pulls aren't a reasonable solution...

Looks like a pretty close match. Of course, you have to find someone
to program the darned things.
