The "6503" used in this machine _is_ a 65C02.  The manufacturer for the
chip (possibly GTE) just has a slightly different product code.

It should not be confused with the original 6503, which was a chip with
fewer pins (and a smaller addressable memory area).  These were
available from Rockwell, and possibly other sources.
