65c802? What's that (looking dumb). The IIc+ uses the 65c02 and one thing you have to be careful of is the accellerator is built into the mother board akin to the Speed Demon card, which is why you can drop an 8MHz Zip into one. Soooo, I'd be careful about swaping out the micro processor. However, if the chip is cheap and doesn't blow the motherboard, what ta heck! Give it a shot. -John
