I picked up 3 of these a while back, I am unsure of what kind of machine they go to. The plan was to use them to prototype on, but then I found some even better wire wrap boards and set these aside. I did not want to have to go through getting all the wire off of them.
They are up for sale or trade if anyone is interested, I am just curious if anyone knows what they came out of. gallery : https://postimg.org/gallery/1tizoqomi/ --devin
