You guys are amazing... Just as I get the Percussive Noise Synth PNS-1a up on
my site you start talking about SN76477s. The PNS-1a came from an article in
the Nov/Dec 1979 issue of Polyphony, with a few changes by me. It uses a
SN76477 a CD4069 and a hand full of parts. It's easy to build and can be used
to create a unbelievable array of sounds. Come to think of it, I think the
article was by John Blacet... hummmm I wonder how close this is to the Dark
Star module?
