I was using old instructions that I had got from a friend that pre-dated Mac-SE where you have to remove a jumper, not cut the R35 resistor. I resoldered the resistor, took out the jumper, and put the 1 Meg SIMMs in slots 3 and four (256Ks in slots 1 and 2). Now everything works perfectly. Boy, I feel stupid. Pete
