In my enhanced (just today!) IIe, I have a Rockwell 65C02 instead of the NCR
65C02 that the IIe Technical Reference Manual describes. From an article I saw
some time in Nibble, I know that the Rockwell version is supposed to have some
opcodes that the NCR version doesn't. Does anyone know what extra opcodes are
available?
Thanx in advance.

I think its just the WAI (wait for interrupt) and STP (stop the clock) inst ructions, numbers $CB and $DB respectively.
