Note It appears to make the IIe more closely compatible with the Apple IIc and II Plus.
Firstly it appear like a 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
  • 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.
For those who purchased the Enhanced IIe new, there were modifications to the appearance of the keyboard, including a darker color to the keys, a smaller size to the characters on the keys, a change to black color for that text, and movement of the character to the upper part of the key.
Also, the power light had the word "Enhanced" or "65c02" added to it, to help distinguish it from the original Apple IIe. (This sticker was also included in the upgrade kit).
