They are 4 by 10 pins. I think the left row of 10 are keyed vertical,
the next row horizontal, then vertical then horizontal, which would
stop you plugging in upside-down.
I can measure them properly at the weekend but I would estimate the
sockets are about 3 inches high and about an inch wide. I will get a
big torch and check the keying as well. The three sockets are labelled
T1, T2 and K and they were originally for connecting a cable to a BCD
encoded Friden Flexowriter which gave tape to card and card to tape
copying, with a printout made at the same time.
