I remember the 1960s. A Univac computer filling a pretty big room. I used to do cards, data entry. It took hours to run the program with my data, calculating molecular orbitals for a rotating molecule around a sugar bonded to a planar nucleoside.
I don't think we shipped a computer like that. Radio controls, however, were available, as well as simple analog devices energized by springs.
I'd have designed a box on a chain with a lid that opens to the side, with a spring-driven scooper to draw stuff in and close the lid. Also the chain would be on a ratchet that woujld retract the box into the hold.
