Can anybody tell me more about this core memory assembly ?
The assembly consists of three wire-wrapped "BICM9" backplanes, one
of these holds four 8K x 9 core memory boards, the other two contain
several modules with names like "M9INH", "M9SNS" and
"M9SEL".
Logic on the various boards appears to be mixed TTL/DTL (!) in
standard DIL packages, most boards are from 1972.
