Clarification:

An enhanced IIe has a 65C02; the original IIe does not.

Most of the original IIes and the enhanced IIes support double hi-res
graphics.  Only the very first RevA boards did not support double hires.
It has nothing to do with the 6502/65c02 chips.  Both work.  (I think the
aux. 64k/80 column is required for DHR.  Either the aux 80 col. card or
aux 64k/80 col. is OK for 80 column text, double lo-res graphics).

The enhanced IIe has the Mousetext characters in the char. generator chip.
The original IIe does not have mousetext, but shows inverse uppercase.  It
again has nothing to do with the 6502/65c02 chips, but the character
generator chip.

An origianal IIe could be upgraded to an enhanced by replacing four chips.
The 6502, char. generator chip, and the ROM CD and EF chips.
