The burner will almost certainly have a read mode. If
it were me, and I
realize this is sort of belt and suspenders thinking, I would read and
display the suspected bad EPROM contents using the burner. You will
likely see the same results, but it should definitely confirm (or
question) your original very fine analysis.

Yes, I will do that Charlie. I've read the docs and hope to get the ROM
burner hooked up and going later today. The process doesn't look too hard.
I've found a source of used and unused 27C16 EPROMS here for a cheap price,
atlthough they won't be here until the end of next week. I've also ordered
a cheap UV eraser, which I will need to use if it's going to be more than a
one-off activity.
If this works I hope to burn a couple of ROMS for an old PET board I have
too. I understand jumpering or some kind of adaptor is needed for these
chips though. Anyway, that's in the future.
