In the 1980s we downloaded games from the radio

I definitely had cassette based games on the TRS-80, but most of the "wireless" transmission in my youth was via BASIC printed in the back of computer magazines. You had to type in the entire app yourself. I did this for basically every app they listed. Sometimes it was like tax prep software, but I didn't care, even though I was like 9 at the time. Yes, it took a very long time. Yes, you could easily introduce typos and bugs.

Doing this is one of my earliest memories. I think I was 5 or 6. I hadn't even mastered reading yet and I was typing a game into an IBM XT clone (think it was QBasic) one character at a time. Don't think I would have bothered with a tax prep program, though. Now that's dedication.

Edit: Could not have been QBasic as it wasn't released until 1991 and I was doing this in 1987-1988. So maybe GW Basic? Whatever came standard on an IBM XT clone from Taiwan.
