NO!!!! Do NOT upgrade the RAM on a 128k EVER! There are few enough unmolested 128k boards around as it is. Between those who upgraded them when they were new and those that were discarded over the years, it has driven the value of an unmolested, functioning 128k through the roof. If you want to do a RAM upgrade then your best bet is to find a 512k/512ke board and put it in and set the original 128k board aside where it will be safe. You can use a Plus motherboard, but then you also have to find a Plus case bucket. I don't recommend using something like a Dove upgrade because those are also rare these days and too valuable to risk actually using and cost too much. What's better is just buying a whole, functioning 512k/512ke/or Plus from ebay if you need a functional compact Mac. They are still cheap enough assuming they don't have any exotic upgrades inside like the aforementioned Dove. I am in the process of restoring a 128k Mac (the original 1984 model that just says Macintosh on the back) myself and I'm down to having to change out 1 RAM chip to make it work after having changed the analog board to get it to power up again. I got a good price on the board and it was easier than changing the now becoming scarce flyback transformer, which was the major problem and usually is the problem in many non-functioning compact Macs.
