Ethan, good advice. I also think that since many of these chips are rare,
it's worth the effort to pull them out of their sockets, drop them into a
burner and copy them out to hex files for archival storage. Does anybody do
this as a practice, or am I overly paranoid? --Patrick

Good thing, too, because the 2532 is not pin-compatible with the 2732.
It's pin-compatible with the 2332 mask-programmed ROM.
The 2532 is familiar to PET owners - it's what you need to drop right
into the open sockets next to the BASIC ROMs. My 2001-N has three:
BASIC-AID, a replacement machine-language monitor, PAICS BASIC Toolkit
and Eastern House Software's ROM-Rabbit - twelve throbbing K of firmware
goodness. :-)
I was lucky enough to fall into a carton of boards that someone else
pulled from some unknown brand of dumb terminal - a 6502 on every board,
plus several 2532s and some wierd stuff like EA-3400 EAROMs. Bonus:
every chip was socketed!
I always inspect stuff from the 1980s for 2532s. They were much less
commonly used than the 2732s. OTOH, if you only need 2K, the 2716
works fine in a PET.
