The EPROMs in one of my machines are at least 32 years old. Reading
online about EPROMs it seems that maybe my old devices are nearing the
end of the life of the memory contents. So I'm thinking I should copy
or have copied the data in these old devices. Am I right?
Thanks,
Eric

Definitely make a copy. Then program a second copy of the EPROMS and swap
them in to confirm the copy. If the copies are good, erase and reprogram the
originals and keep as a spare.

Also replace any memory backup batteries while you are there.

You will probably be dead before you need the copies.
