To return to the original question, I beleive the contents of those PROMs
are in the printset. Just not obviously.
The APROMs are part of the microcode, the format of the microcode word is
in the pritnest I looekd in on bitsavers. As is the microcode binary
listing. So you have to extract the appropriate bits from that listing.
It's only 256 locations...
The PROms are 256*4 bipolar PROMs. Various companies made them, they all
should be equivlaent when reading, but nor when programming. So if you
get some, make sure your programmer can handle that brand.
