You'll need this toplay punch your cards right.

A most curious machine.
Humungous card rack in the electronics bay under the table, with printed circuit cards that have 0.1" pitch fingers on one side & 0.156" fingers on the other.
Really had to get creative to make an extender card for that.
Which helped find the single solitary electronic fault we ever had with it: a failed diode in the circuit that controlled the printing along the top edge of the punched card.

Another gem: (no, not GEM) yet another very early PC, the MCM-70.
It used an 8008, the predecessor to the 8080, and was programmed in, wait for it, not C, not Basic, not FORTRAN, but APL.
Dunno if it came with a special golfball for the printer though.
