My experience in that was with a special "computer system" back in 1966 that my high school had, which had no monitor (only red lights for register contents), no hard drive or floppy (only punched paper tape to save programming) and only using 1s and 0s (requiring us to even program it to multiply and divide), and making up our own mnemonic programming language, on the fly. That's all that was out there
I just want to use today's devices now ... :-) ...
