There were covers for the boards that allowed room for several inches of wiring.
For those who never saw the Tinkertoys®,, the concept of having to wire each column instead of field start and length may seem strange; it seemed normal at the time. OTOH, I would never want to go back to any of the relay or vacuum tube equipment I used, although I have fond memories of some discrete transistor machines. -- Shmuel (Seymour J.)

You put an overlay over the board (depending on what you were programming) and inserted wires between the holes based on the overlays. My father programmed these things for a bank on Long Island NY. The wires were of various lengths depending on how far they had to reach. They were mabe 12inches by 12 inches, and went into a receiver, and then were snapped into the machine. After I went to 360 Common I/O school, I went to work for Sorbus for awhile and had to deal with them there, but I never could program them.
