Yes, a remarkably few number of modules make up a huge bulk of the population. Of course there are some rare types, like the high speed versions or the ones that IBM farmed out, but they can mostly be ignored. > So, when I was talking about making replacement SLT MODULES, I meant to > fabricate tiny 1/2" x 1/2" PC boards with 12 leads, that could be mounted > where the failed small SLT module had been. Yes, those are the things that are really pretty common. > In IBM terminology, Chip, module, card, board, gate. I suppose chip level repair might be possible with today's SOTs, but I would not want to do it! -- Will
