<div>First poster here with some info on a discontinued chip.</div>
<div> </div>
<div>I picked up a couple from unicornelectronics recently and built a complete synth with the heart of it being the SN76477 chip. These crazy lil 28pin dip chips were once used inside old Mame Arcade machines. You can find a good amount of info on them now as well as various schematics. Anwyhos, I figure it might interest some of you folks so here are a few links in regards to what I'm blabbing about.
