Let me not forget "punch machines" (024, 026 -- actually printed the contents of the card on top of the card, 029 -- a bit more modern) and there used to be rooms filled with these machines -- usually 10 - 100, depending on the size of the business. This was where all paper was transcribed to data cards.
The 029 had a tiny microswitch which would shut off the card feed when the output hopper was full, unlike the 026 which had a regular-size toggle switch that was positioned at the top of the output hopper so it would trip when the hopper was full and shut off the card feed. A small piece of ordinary Scotch tape was sufficient to hold down the microswitch and prevent the blank cards from feeding, and if you recall when they used to advertise it as "Scotch invisible tape", in this use it pretty well was . . .

Almighty Ruler of the all, Whose Power extends to great and small, Who guides the stars with steadfast law, Whose least creation fills with awe, O grant thy mercy and thy grace, To those who venture into space.
(Robert A. Heinlein's added verse to the Navy Hymn)
