Synopsis

Invisible Clock continuously shows a 24-hour digital clock in the lower screen border. It's controlled via SYS commands: SYS 49152 displays the clock, SYS 49152,"hhmmss" sets the time (leading 0 – reverse video), SYS 49152, color changes the color (0–15). It uses raster interrupts – TI$ becomes inaccurate while running. Sprites 0–2 are used and $0340–$03FF is reserved for sprite data. After RUN/STOP-RESTORE, the display must be re-enabled.
