Sound Demo

demo Open · freely redistributable

A self-authored, public-domain Atari 800 cartridge (8K, $A000-$BFFF). It installs its own ANTIC mode-2 display list, prints "SFOTTY PIE SOUND DEMO" using the AltirraOS font, and programs POKEY for a steady ~394 Hz pure tone on channel 1 (AUDCTL=$00, AUDF1=$50, AUDC1=$AF). A tight, fully-visible target for the debugger: single-step the boot, or watchpoint the POKEY audio registers.
