Yup. I don't know how much logic is in a 1401, but probably
in between 500 and 1000 SMS cards. Apparently, getting the
CHM 1401 running was a multi-year project. The 7094 has
11,000 SMS cards!!! Completely beyond comprehension. Given
the technology, I'm not sure how IBM kept these running when
NEW with a box of spare cards on site. And, given how my
uVAX-II deteriorated over only 21 years of use (biggest
problem was the backplane finger contacts slowly got
unreliable), I can't imagine what kind of HELL one would go
through with 11,000 circuit cards! Holy Moly!
