((((There is no such thing any IIc firmware that reports "1". Further-
more a motherboard swap is not required, you can do a ROM chip swap to
upgrade with a simple modification (cut one trace with a blade, close
another with a drop of solder). Here are the possible values you can
get, typing what I mention above--and what they are:

"255" = original ROM, only supports external 5.25 drive
  "0" = UniDisk 3.5 supported
  "3" = memory expansion motherboard
  "4" = memory expansion motherboard with ROM bug fixes
  "5" = Apple IIc Plus)))))

Where can I find the source listing for these roms, because
I have a version 3 motherboard and I would like to program new
ROMs with the bug fixes as in version 4. I,ll also need the type
Rom chips used.
