How can I tell for sure if my //e is enhanced or not? Look at the 6502 microprocessor chip on the motherboard. If it's a 65C02, and if you or a previous owner didn't change it, your machine is enhanced. A less sure sign is to look for the word ENHANCED in black type on the little power-light panel next to the open-apple key. > 2. What exactly does this upgrade consist of?

The microprocessor, is changerd, as I said, from a 6502 to a 65C02. One of the ROMs is the character generator - it replaces a duplicate character set with Mousetext. The other is the CD ROM, (memory tells me) and it provides some enhanced screen and interrupt handling. Sure, you could do it yourself - all you need is the parts, which you can get legally only from an Apple dealer, or from a dealer or mailorder house that will sell you the kit. I have seen the kit advertised in A+ for $45.00. If you're not certain of your ability to change chips without mucking it up, pay the $70.00 for your peace of mind. If you pay it, then your Apple dealer will support the machine if something goes wrong. It's cheap goodwill.
