If it's BASIC 4 and dynamic RAM chips, it should be 4K ROM chips, and
the EPROM equivalent is Texas Instruments TMS2532 or equivalent. Note
that this is not the same as the more common Intel type 2732.

It depends on exactly what type of PET you have. But I'm not sure
there's a whole set there, for the later PETs.
I *think* you need:
kernal-4.901465-22.bin
basic-4-b000.901465-23.bin
basic-4-c000.901465-20.bin
basic-4-d000.901465-21.bin
and possibly one other that I don't see (901465-29 or equivalent). I
can't remember what's in the E000-EFFF space. The best thing to do is
look at the ROMs you have, see what the numbers are, and try to match
them. As far as I know, you can't mix parts of sets.
