Do you have an AY-3-89xx or SN76489 in your stash ??

Just curious about how many of you have the AY-3-89xx series of digitally programmable sound chips lurking in your parts bins. I have a bunch, 20, I am really looking to do something with and wanted to hear some stories of your experiences with them.

Here is a couple of reference web pages you can get good information on, data sheets, and music with these cool IC's

I also have a bunch, 25, of the SN76489 chips also. It's close to the AY series minus the ENV GEN, 8 bit ports, and has only 10-Bit tuning resolution (the AY's have 12 bits and thus can be more "musical". The noise generator is slightly different also.

So how about a bit of chat about these chips

I had a soundgenerator for zx spectrum once that was based around one of those AY-3-89xx chips....

oooh- that could be a little close to the bone. After initially hearing the SN7 then the SID, the AY was a real disappointment to me. I remember it being embedded within the BBC Micro (which was shit anyway! hehe ). I remember trying one sunny afternoon trying to get it to make anything interesting!!

However, I do seem to remember that it responds well to circuit bending and can also hake some fairly groovy Human League like zaps So don't let me stop you fiddling

Perhaps a project could be championed that involves lots of banana sockets and weird inputs- not far off something looking like a Tandy/Radioshack 100 in 1 projects kit?
