I remember once in the early 80s typing in a very lengthy program listing from Byte or Nybble magazines on an Apple ][e.
It wasn't BASIC or even Assembler, but machine code!
It didn't run at first so I printed it all out (on 15" wide green bar paper) and on several bus rides to and from school would compare the magazine code to my own print-out until I found the few bytes I had mistyped. Checksums would have been nice!
IIRC it was some kind of music program that let you type in melodies and play them back on the PC speaker. I took a melody line and a bass line from a song I was writing at the time and typed them in on two neighboring PCs in the university lab. When all was ready, I pressed the two Enter keys at the same time, and after weeks of work had several seconds of glorious full-volume square-wave harmony! Formative moments!
