Matrix Rain for Atari

I haven't seen the new movie yet, but I was in a mood to do something this primitive.

  • Matriculated Rain: matrix.atr: Download, unzip, load in your Atari 8-bit computer or emulator of choice (Atari800MacX: ⌘D, select this as D1), and reboot (Atari800MacX: sh-F5). There's probably some way to ESCAPE.

It'll go into attract mode eventually, which I think is cool, add 11 POKE 77,0 to disable it. Or any key that doesn't exit will clear it.

Not any really interesting coding tricks, except I replaced POSITION:? with POKE for speed. I use PEEK(764)=255 and then re-POKE it to test if there's a waiting key, but then use GET to read it in ATASCII instead of scan code.

(updated almost immediately: I realized on XL machines I can turn on accented characters instead of graphics blocks. Take out the POKE 756,204 line if you don't like that.)

(updated 2021-12-24: I made it pour in from random starts, rather than top of screen, looks somewhat more like the old intro.)
