I got the casing open and the logic board removed with no trouble. The first two SIMM slots had four 256K boards in them, as it should. I inserted the two new boards into the third SIMM slot. When I closed up the case and restarted the Mac, I got the sad mac sound, along with a strange checkerboard pattern on the screen. I then tried placing one board in the third slot, and the second board in the fourth slot. Same reaction from the computer. When I removed the new boards, it went back to normal. Am I doing this totally wrong? I was grounded the whole time by a wrist tap, so I don't think I damaged the boards or the Mac. Any advice would be appreciated.
