Well, having a backup of the PROMs is surely a good
idea for 2 reasons :
1) If the rest of the board is standard parts (even if they are failry
rare ones), then shoulc something fail you have a chance to get the
replacements. If it's one of the standard parts, you can hunt for
another board that used it (not necessarily from this machine), if the
PROM fails, you can burn a replacement.
What do people do regarding microcontrollers (old or new) with embedded ROM? I
mean an EPROM or PROM's just address lines and data, so reasonably easy to
dump - but presumably life's a bit more difficult when the ROM is local to the
CPU...
