Commodore 64 videosynth test

This was a test of using the commodore 64 home computer as a video synthesiser in around 1985. The patterns are created by direct manipulation of the VIC display chip reading a paddle input. This followed on from a similar attack on a Vic20 home computer which was used live at the Sedition festival in 83. In fact I recall the Vic20 was a better noise box (hint) but I do not have any surviving footage. This recording was made to betamax late in 85. Disturbing the display list directly went outside the usual border of the C64 image. After this I tried to gain more control over the results but when the Amiga was released abandoned work on the C64. The first Amiga work we made was Hot With Fleas in 1987, using the 'lm' or longmovie UNIX software. Another time...

It was Daisy Bell. I remember BBS sysops kicking people off their boards for uploading it claiming that it caused the 1541 to go out of alignment.

As far as POKEing into the VIC chip you can really get the C64 to do some great things including an accidental crash. I wrote a program that did a similar affect by just poking randomly and I had to skirt around what would crash it and what would not.

Looks so cool! :D

No this is done by POKEing values into the actual VIC display chip. I did better stuff, but this is something I have on video.
