This had to do with a bug in the original Mac II ROMs, which Apple would swap for you gratis if you asked. Unfortunately, I can't for the life of me recall the nature of the bug except that for most people it was rather obscure (maybe it only showed up under A/UX?). Does anyone recall the details of this? Note also that the Mac II ROMs are socketed, not SIMMs, but were swapped nonetheless. It's quite easy to swap a socketed chip, really. Does any Mac have soldered-on ROMs, or are they all either socketed or SIMMs and therefore at least theoretically upgradeable? --John -- ** John Scudder ** Merit/NSFNET ** jgs@merit.edu ** no amusing quote ** ** Disclaimer: I speak for myself, not Merit. **
