I just saw a number I recognized...or at least it looked very similar to a
chip I'm using for a doorbell...I'm using an AY-3-1350.  I bought it from
Radio Shack a number of years ago and never used it for anything.  It's a
melody synthesizer.  It has 25 preprogrammed tunes and 3 chimes.  The spec
sheet that came with it is now well worn, and I can't read all of the values
on the sample circuit schematic on it.  Can anybody tell me where I could get
similar specs on this chip, and possibly even a copy of the sheet that came 
with it from Radio Shack?  They don't carry the chip any more, by the way...

If anybody's interested, the circuit amounts to a power supply that switches
on automatically when a doorbell button is pressed, and powers down when the
chip is done playing a tune.  Also 3 small circuits that set pitch and speed,
a small amplifier circuit for the audio output, and last but not least, a
set of swiches that choose which tune is to be played.

If you can tell me where to get specs, please mail me directly...
