This article describes how to convert a Gottlieb pinball system from 2332 to 
2532.

I don't know how relevant it is to CBM floppy drives, but it seems to have 
something to do with chip select lines? Perhaps the PET itself was designed 
with EPROMs in mind so it can handle either ROM or EPROM, while the drives 
weren't. Anyone with a floppy drive handy and some 2532 to program could 
verify or dismiss this before going further to see if an existing ROM-el 
would work.

Best regards
