Intersting to note: many times i have used eproms in place of these proms.
Usually, flash parts are faster, so better suited to the task.

Loader roms:
You may be able to get by with that on loader roms. I've never found
eproms that were functional & pin compatible. What ones did you use for the
1K variety?
Microcode:
I doubt seriously the eproms would be stable for microcode. HP specs 5ns
speed parts for the microcode; what eproms work and can hit those speeds? I
suspect this is one of those "might seem to work" but is a really bad idea.
