Re:The mysterious heart of the Roland TR-808 drum machine by squarefoot on Monday July 30, 2018 @06:37PM (#17648799)
If you're interested in claps and cymbals you may find interesting the Boss DR110 schematics here: http://www.freeinfosociety.com/electronics/schemview.php?id=...

Especially the voicing board schematics is simpler than the 808 one. Interestingly they used a shift register for noise while cymbals are still made using dissonant oscillators with cmos gates. The schematic though is much easier to read and understand. That drum machine sounded close enough to the 808 to gain its share of popularity when a couple decades after that sound became mainstream, and of course I was stupid enough to sell mine for cheap just before that moment.
