See the RM Wiki site for easy to follow set of install instructions to ensure quick setup and unlimited Tech Support should you have any questions.
Apple’s part number of the Enhanced ROMs:
CD – 342-0304-A
EF – 342-0303-A
If your CPU has ’65C02′ or ’65C03′ printed on it and the numbers of your ROMs match the numbers listed above then there is a good chance your IIe is already Enhanced and you don’t need this kit. Perform a Self Test (Control, Closed-Apple, and Reset) and you should see low-res squares on the screen. If you see horizontal bars then you need this kit.
Chips pictured may be different than the ones you receive but will be 100% compatible.
