Mac 128K board repaired

Hi, All, For those that might be following the saga (and especially for those who chimed in along the way), I wanted to let people know that the board is running and boots Finder 1.1g off of suitably-formatted floppies (single-sided MFS). Despite numerous reports on multiple Mac discussion lists, et al., A Sad Mac with 6 bits set was corrected by replacing the 6 indicated chips. I can only imagine that the numerous reported failures that were unrepaired by replacing the RAMs were problems with bus buffers or some other thing that dragged down multiple bits on the data bus, or perhaps traces/vias damaged in the repair pricess. In my case, thankfully, it was no more than diagnosing and replacing a few chips (FWIW, I was able to verify that in advance by dry-fitting known good DRAMs on top of the bad ones and observing a positive change in the power-on diagnostics). So that's done, and now it's time to clean and lube the eject mechanism on an old 400K drive, then turn my attention to getting an Imagewriter I working again. I'm sure I can make a cable but with any luck, I already have an official Apple cable in my box of old Mac parts. Not sure about ribbons, though. Thanks again for all the suggestions. -ethan
