thing 21: Syntho '77

In my junkbox I found this vintage 1977 (or so) 76477 synthesizer chip- this model used to be used in arcade machines. It was gonna be another Matchbox Synth - you can see I have the case all prepped - but, whether because it's old and broken, or because I wasn't using it right, I couldn't get any sounds out of it except for these.

Still, you may not have seen and heard the last of Syntho '77!

p.s. this is my 4000th photo on flickr! (counting private ones)
