Apple II Cycle-Counting Fireworks demo by Vince "Deater" Weaver vince@deater.net http://www.deater.net/weave/vmwprod/ Loosely based on a BASIC program by FozzTexx Usage: BRUN FIREWORKS press any key to toggle sound and restart This code uses cycle counting extensively. This is how HGR and 40x96 LORES are mixed. HPLOT0 was made cycle-invariant, which was a pain. HGLIN (allowing HPLOT TO) was intended to be too, but I ran out of interest.
