My '40 upgrade kit arrived recently, and I spent some time installing the new board this past weekend. I had only one strange thing happen... The memory diagnostics found a bad simm (in bank 0) when I booted the '40 for the first time. Swapping all of bank 0 with bank 1 moved the problem to bank 1, so I know that the problem was not with the simm slots on the board. However, when I re-installed the '30 board, the memory problem went away! Can a simm be "marginal", and if so, what is it about the '40 board that might tickle it enough to fail? [to forestall some obvious questions: I _had_ installed 2.0, I _was_ properly grounded, I used the special simm tool to remove the chips, they were seated firmly in the new board, and the 8 1-MB chips that were in the cube were original NeXT memory.] ps. watch this space for an update to William Smith's simm price guide. -- Dave Paulson dpaulso@relay.nswc.navy.mil (work) Synetics/NAVSWC talos!SandBox!dave@uunet.uu.net (home,NeXTmail)
