Cassette tapes and turbo loaders (though a bit after the PET) on the C64 was... Interesting
Sitting with a screwdriver to adjust the tape head, so that the lines looked good enough that the load would probably succeed, felt quite sci-fi in the beginning, but after doing it the 50000th time, you couldn't wait until everyone was using disks. What a PITA.
.... And I have a feeling that it wasn't necessary until someone started tinkering (IT'S FASTER THIS WAY. I KNOW IT!) or had a broken head, then when others got tapes from him they needed to adjust, then they lent tapes to others and THEY would adjust their heads, and so on and so forth. A bit like a very manual virus! :)
