LOL. That reminds me of the days I used to load a primitive boot

load the next phase of the boot loader through the paper tape

heart. Those were the days! The machine had core memory also.
Not enough of it tho!
Paper tape? You were lucky...
About the hardest I've done was using a hex keypad to program some
obscure ladder-logic system as part of a class. Practical value of
that exercise: zero.
