Japanese Jason has been planning this drum machine since the 90s and it has finally come to life. The drum machine is built from eight Famicom consoles and a Roland 606 drum machine. All of it was nicely mounted in a flight case. He also documented the entire process here. Audiophiles and vintage Nintendo connoisseurs around the world salute you, Jason.
