I have a core memory module from some Burroughs
machine. It is a large
plug-in PCB about 16 inches square containing address & inhibit drivers &
such. Mounted to this is a near-same-size daughter-board containing the
sense amplifiers and the folded planar array of cores underneath a metal
shield.
It is organised as 32 KWords, 20 bits wide.
Any suggestions as to what machine this may have come from?
Burroughs made several successful solid state accounting machines
before branching to full computers. Some of these had core memory and
were made in the 1970s.
I knew a service person in Portland who maintained these and also
serviced the early Vector 8 bit computer market in the 1980s.
