Bought this mint original Kaneko Air Buster PCB from my friend Corrado:
PCB was working fine but sound samples (drums, bass line, etc..) were played sometimes randomly other times in a bad way:
In this PCB (and a lot of other similar audio hardware) samples are played by the OKI MSM6296 chip which take DATA directly from the ROM that I dumped as good.Connecting an external AMP to pin 36 of the OKI6295 (this pin is the digital-to-analog converted signal fed into the UPC324 OP-AMP, you can download its datasheet here in the downloads section ) I had the same issue so this convinced me to replace the chip (with a rebadged one but it’s the same):
This restored fully music/FXs.Job done.
