%c%Applesoft Games
* Got inspired by playing some games.
Can I do this on the Apple II?
* Kerbal Space Program
Surprisingly easy (for 2D)
ATAN bug in tokenizer
* Portal (the Valve one)
15-minutes of internet fame
Also surprisingly easy physics.
Was disappointed in music quality
of credits. Started AY-3-8910
* Also did a Uthernet webserver in
BASIC. Worked well, but memory
copy slow if not done in 6502
