Simple Falling Sand in 6502 assembler

[darvidanoar]

I'm learning 6502 assembler and what a machine to learn on

As my first attempt at doing something on my new Commander X16, I thought I'd have a crack a very simple Falling Sand program.

The objectives for me were to learn how to:

• use the ca65 assembler

• communicate with the VERA

• set a graphics mode

• plot pixels using the VERA

• read pixel values back from the VERA

It's not mind-blowingly fantastic, but I thought I'd share this anyway so that others who are learning might have some sample code to look at.

That's a cool program.

I took the liberty to assemble it and attached it here as Try It Now!

Couple ideas:
1) Ability to drop sand in front of previously dropped sand.
2) Ability to adjust speed of dropping sand.

First thing I thought of while messing with this was that it was a neat way creating mountain ranges.
