Hello World on 8-bit Atari Assembler
I use Altirra as an emulator for Atari 130XE. Printing "Hello World!" on the screen using Atari Assembler was a task on my Najm Atari 65XE checklist since the early 1990's. I finally had the time to refresh my 6502 knowledge and use it on a recently found book containing Atari's memory mapping and the addresses of the CIO vectors. The result is here.
