The four pages of this document were created using the output of a short 10-line, BASIC program. The author methodically noted down four sets of numbers for each ASCII character. This information nicely supplements the August 1979 issue of the Arcadian's music coverage from Robert Hood (American Concert Frequencies) and the second part of Chuck Thomka's music tutorial, The Music Synthesizer.
Bob has written the name "Levin" across the top of this letter. However, it seems to be signed by someone named (if I'm reading the signature correctly) Randy with a last name that begins with "F."
A five-page program that is purely Chuck's own concoction. This program uses all but about 150 bytes of memory and is somewhat involved, but is informative as to the workings of all the possible '&' commands.
A single-page modification to an existing Bally program which allows easy and quick changes to '&16' through '&23 commands [the sound ports].
