Guess what! It's tomorrow and the project is done.

It was a bit harder than I thought it would be. Certainly not because it was something I was unfamiliar with. I can change these things out in my sleep provided everything goes smoothly. Old man Murphy had to get involved. The screws that held the power supply in place in the newer unit were rusted and they weren't going anywhere. So I removed the motherboards from each unit and switched them out. It's a good thing the bottoms of the A2S2064 (early 80's IIe) and the A2S2128 (late 80's IIe) are interchangeable. If these two computers were dogs they would be classified as mutts. I have an early model Apple IIe base plate that now has a later model A2S2128 on it and then there's an A2S2064 that's sitting on an A2S2128 base plate. They look right but the model numbers on the bottom are wrong!
Back to those rusted screws. I wasn't going to leave them like that. I ground the heads off them, pulled the sealed power supply out, took the bottom off it so I could get hold of the clean end of each screw. There were ten nice clean screws holding the bottom on and they came out without incident. Using a small vise-grip pliers I gripped the end of each of the rusted screws and twisted them out one by one, put the power supply back together with six screws holding the bottom onto it. I used the other four to secure the power supply to the computers bottom plate. Both machines work perfectly even if they are slightly mixed up now.
