Hmmm the modules look familiar, we used to have a Honeywell 3200 (not
sure for certain of the model) at work that we ran till 1988. It used
memory modules like that ... I've got a couple I saved as souvenirs. I
would have to dig them out of my attic to be sure. We also had three
level sixes, one in our main plant and two at other plants.
