No, you bought magazines back then which had pages and pages of printed source that you typed in. And hoped that you didn’t make mistakes. That’s actually why I learned debugging before I learned to code ;)

And this also was the way I earned the money for my second computer - I wrote about 50 games on my own for my first one, some of which I sold to such magazines by saving them on casette tapes with a modified casette recorder. I wrote so many games, they published them under aliases…
