The kit includes:

  • 2 x PCBs: the Mainboard and the IO Board
  • 2 x MUX/SH board
  • The µC, a Atmega1284P pre programmed with Firmware Nava v1.0
  • 3x program EPROM 27C256 with the sound of HitHat, Crash and Ride as those present in the original TR-909.
  • 36 x M5218L Mitsubishi. Those are the original TR-909 OPA
  • 2 x HD14006BP 18 Bit static shift register used to Noise generator
  • 1 x AN6912 Quad comparator. HandClap envelop generator identical to that of TR-808.
  • 1 x BA6110. This is the only component that we have replaced the original TR-909. The original HandClap VCA is a BA662 manufactured by Roland, but today very expensive and rare. After several sound comparisons and operating the BA6110 makes an excellent substitute for BA662.
