Bars & Beeps (6502 demo)
demo Open · freely redistributable
Bars & Beeps is a small open demo written for this build in 6502 assembly. It sets the LCD controller registers, fills the two video bitplanes so all four grey shades appear, scrolls the screen via XSCROLL every frame, and programs the AY-3-8910 with a looping arpeggio so the machine is visibly and audibly alive on boot. A clean, freely-redistributable target for the in-browser debugger.
