PDP-8 /e/f/m memory

[Paul Anderson]

I checked with my friend, and his coworker, who died a few years ago,did
make some 32k mos boards for the 8E. He is going to check to see if he has
any complete units, unpopulated boards, parts, and documentation for
them.This will probably take a few days.

Thanks, Paul
