Question: what is "typing games from magazines?"
Later, magazines would ship with floppies that had the free software on it.
EDIT: Still totally fascinated by this. I asked my husband because I remembered that he had a much-beloved Spectrum when he was a kid and sure enough, he had digitized Your Sinclair issues on his iPad and he showed me several examples of games in Basic and hex. Super cool.

Have been following it for years and would recommend reading it all the way through. Maybe even get an idea for the next project :)
However, debugging it helped to learn the language. :)
Dr. Dobbs Journal was probably the king of source code listings in magazine format.
Pre-Internet, there were some remarkable mass-distribution Unix magazines with significant source code for utilities: Unix Review and Unix World. Even today, the back issues would be useful.
I remember lusting over the AT&T 3B Unix machines advertised in those, but never could afford one. So I waited until VAX Unix in uni (the arts dept. had an unused one), then SCO and Linux.
