Boy, are you bringing back memories and you made me look to see that my
collection of odd old stuff wasn't damaged by the recent flooding we've had.
I know that I have a "64" bit handwired memory board and I couldn't find
that but did stir up a Fabri-Tek board that I think was 64 K but that was an
entirely different generation. I did get to tour the SAGE system computer
at Madison's Truax Field in 1958. They had the loudspeaker on so you could
hear the computer work. A monster pile of vaccuum tubes!

that had one megabyte of core memory. The stuff was still in use in the
late 1970s 1MB was a lot of RAM in 1975.
