Hello all,
I have an old memory patch panel, probably a diode matrix. Estimated to
be from the early 60's, maybe IBM?

I have 3 kinds of diode plugs that fit in the sockets
It has white plugs with one type of diode in it.
It has brown plugs with a different type of diode in it
It has grey plugs that will be a short.
So it appears that each location can have one of four values
open, short, diode1 or diode2.
I am interested to find out more about this - any information such as
documentation, model, or what it belonged to would be helpful.
Thanks!
