A Chameleon (sp?) chip is the figment of someone's vivid imagination.
I don't believe that such a chip exists, yet.  (I'm sure I will be
corrected if I am mistaken.)  What the chip would do is up to the
programmer.

If the programmer wishes s/he had a 65C02 to program, then the chip
will function as a 65C02.  If the programmer desires a 68000, then
(presto) the chip thinks it is a 68000.  Want an 80386?  Just tell the
chip to emulate one and there you go.

The idea behind such a chip is to design a computer that can emulate
various other computers with different chips.  If one chip can emulate
all the other chips then that is the only one you would need.
