I remember one place I worked where they started getting punch machines that would key to memory first and only punch physically when the operator said so. In a classic piece of thinking well inside the box, they gave the first ones to the best and fastest operators. Guess what? They were the operators who didn't need them, because they didn't make mistakes.

Those were the days. Sit and have a nice cup of coffee and a cake while the operating system loaded from paper tape. Almost as long as it took Windows Vista to load.

You'll need this to ~~play~~ 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.

Inventing the PC: The MCM/70 Story: Amazon.co.uk: Zbigniew Stachniak: 9780773538528: Books

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.
