Really? Are you sure? I didn't know that!

I think that was done with punch cards, one for each move. There was no
memory storage as we know it today.Memory was limited by the number to
tubes in the control. One tube for each two bits of data. They did
have mechanical relays the were used. Think pin ball machines.

No, I don't think so, John. What you're describing sounds like some of the
commercial machines that came out in the mid-'50s, like the J&L Binotrol,
and the G&L Numericord.

I don't have access to the old reports anymore, but the MIT machine was
described as a computer-controlled machine. It had a vacuum-tube computer
controlling it. I don't recall if I ever read just what the functions of the
computer were.
