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!
