[vcf-midatlantic] Core Memory Purchase

[John Sully]

I'm planning to resurrect some old core memory as a hobby project.  I was
wondering if anyone with experience on getting this memory working could
provide some insights on what I should look for.

EBay seems to have a large number of expensive ones that don't appear to be
in working order - along with some much cheaper (relatively speaking)
russian made stacks.
