Enhancement kit for the A2e

My question is what did the Apple //e Enhancement kit give to enhance the //e?

The upgrade kit (for previous IIe owners) consisted of four chips that were swapped in the motherboard: The 65c02 processor, with more assembly language opcodes, replaced the 6502; two more chips with Applesoft and Monitor ROM changes; and the fourth a character generator ROM that included graphics characters (first introduced on the IIc) called "MouseText". The Enhanced IIe ROM changes fixed most of the known problems with the IIe 80-column firmware, and made it possible to enter Applesoft and Monitor commands in lower-case. The older 80-column routines were slower than most software developers wanted, they disabled interrupts for too long a time, and there were problems in making Applesoft work properly with the 80-column routines. These problems were solved with the newer ROMs.

I have a CMD micro G65sc02p-1 microprocessor. [...] Also would this processor work in the stead of a 65c02?

I bet it would.
