At the Vancouver Mini Maker Faire, this old Apple //e was showing a simple demo:
10 PRINT "Maker Faire ": GOTO 10
I decided a green-screen Matrix effect would be way cooler, so I busted out some quarter-century old skillz to whip up this demo.
We downloaded an AppleSoft Basic PDF manual onto our phones, but it turned out not be necessary. I remembered about half of what was needed and another guy supplied the other half. Most of AppleSoft Basic is burned into my neurons -- I started programming when I was 11.
I put the source code up on Github. I find it hilarious that I'm putting an AppleSoft BASIC program on Github.
