I dunno how old you all are, but I used to have a subscription to K-Power when I was a kid.  They published programs in Basic for all popular home computers of the era (Apple, Commodore 64, TRS-80, IBM PC, Atari, TI 99/4A) for kids to type in and run.  Might find some useful code snippets!

I don't remember that particular magazine, but certainly had many type-in magazines and books back in the day. I've recently rediscovered the wonderful range of Usborne type-in books. Listings are ultra "vanilla" and suitable for many 8 bit platforms. Also perfect for building upon.
