OK, there are hundreds of different SLT
"cards", ie. the PC boards. But,
reading some FE docs on bitsavers, it seems that all SLT 360's were built
with 95+ % of the SLT "modules" consisting of only 6 types.
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!
