Comments
The Apple IIe Enhanced was nearly identical to the original IIe, the only difference being four socketed chips had been changed on the motherboard: 65C02, CD and EF ROMs, and the Video ROM. The IIe Enhanced has an "Enhanced" or "65C02" sticker placed over the keyboard power indicator to denote itself. The primary purpose of the update was to make the IIe more compatible with the Apple IIc released a year earlier. The IIe Enhanced uses the CMOS based 65C02 CPU, a new character ROM for the text modes, and two new ROM firmware chips. The new ROM added "MouseText" characters first introduced on the Apple IIc and it also fixed various problems and speed issues. Apple sold an official upgrade kit to owners of the original IIe that consisted of four replacement chips and the "Enhanced" sticker.
