*** USEFUL COMMODORE 64 POKEs and PEEKs *** Compiled from Usenet postings, magazinge articles and other Commodore Users by: Paul Panks (dunric@gmail.com) 04.04.2002 ------------------------------------------------------------------ From COMPUTE!'s Gazette THE PROGRAMMER'S PAGE: November 1988 "Notebooks and POKEs" - Randy Thompson ------------------------------------------------------------------ Many of these POKEs were sent in by Victor J. Fogh of Mariposa, California. Others were taken from the COMPUTE! book, MAPPING THE 64 - another great source of notebook material. The rest are the result of experience and expiramentation.
