Hi!

Whoever buys these chips might be interested in the scanned SN76477 articles on my webpage http://www.ullrich.at.tt under 
Music/Synthesizer DIY or the direct link (but then without the menu on the left) http://synpro.heimat.eu/f_music3.htm

Some are in German but schematics are useful and international I think.

Ciao
Peter

Betreff: [sdiy] [Free for cost of postage] SN76477N sound effect chip

Hi,

I moved house recently and in the process had do to do some consolidation of my junk^h^h^h^h treasure collection.

In the process I found an antistatic tube with two TI SN76477N sound effect chips in it.  If my memory serves me correctly, they were purchased new in the early eighties and I think are unusued, but it's possible I had them in a (socketed) project at some point.

I lack the time to test them so no way of knowing if they work now.  I would expect they are fine :)

One or both free to whoever wants them if you'll cover the postage from Canberra, Australia to wherever you are :)

Cheers,
Hugh
