I spent a lot of hours typing in those game programs.my computer could only save to tape so the chances of even finding one of those tapes now after 40 years is unlikely. It also let me play games off cartridge so at least not all games required me to rewind the tape to replay them again.
back then you could buy magazines with games to type out. Imagine that now... okay, lets print the 10000 page magazine and sprinkle a few ads between the lines of code.
