The 3165 used core, as did the 3155. The solid state memory came in
later for the big machines then it did for the small machines. It was
the models 158 and 168 that used semiconductor memory, unless you were
referring to cache.
Of core, the 2065 used parity checking while the 3165 used ECC, so the
impact of memory problems was greatly reduced.
>Very true, but not obvious from the marketing material at that time.
I tended to read CE manuals and logic manuals; the marketing manuals
were too hard for me to understand. Or do you consider IBM Systems
Journal and The IBM Journal of Research and Development to be
marketing manuals?
