Is it possible to damage an EPROM by exposing it to UV light for too
long? What if a portion of the EPROM stays unprogrammed ('FF') and the
chip goes through some program-erase cycles? The unprogrammed area
should fail sooner or later, shouldn't it?
The old ceramic packaged one's must be getting hard to find these days -
can
flash ROMs be put in their place?
how long can those old ceramic+window things keep their memory? Some spec
sheets indicate some random number of decades, but is any of this true?
I have an old XT-turbo clone with UV EPROMs that still works.
