Anybody know details on this diode matrix patch panel?

[Bob Roswell]

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!
