   PC that's
got my ROM burner/reader, and read each one (if the
 ROMs aren't too large a size for my Needham unit). I'm assuming
 I'll see all 00s or all FFs (or maybe something like FEs) if
 they're blown; been a long time since I've looked at popped
 ROMs...  
   What kind of ROMs does it use?  Another possibility might be to find
 someone with the same model of PR1ME (how rare are they?) and checksum
 the ROMs & compare them...most PROM burners will generate checksums,
 but now that I think of it, PROM burner manufacturers have yet to
 standardize on a checksumming algorithm so it'd probably be useless
 unless they're summed with the same make/model of burner. :-( 
My ROMs are fine; they read OK and I can provoke an error condition
that results in a message to the console, and said message string
resides in one and only one place- the microcode ROMs.
