Apple II Cycle-Counting Fireworks demo
by Vince "Deater" Weaver

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.
