+9V 10 to 15ma

Dual Stepped Tone Generator. The legendary Atari Punk Console, This 2 times with 4 CV's in controllable by then the sound of chiptune of Atari 2600.

The APC is one of the most simple sound-producing designs, with a very low part count. The circuit uses 2 timers in one chip, the NE556, which is in fact a double 555 timer.
The Atari Punk console is an astable square wave oscillator driving a monostable oscillator that creates a single (square) pulse. There are two controls, one for the frequency of the oscillator and one for the width of the pulse. It also has CV-inputs for both of these.
The characteristic 'stepped tone' output of the square wave when turning the pots is reminiscent of the synthetic sound of old game-computer sounds, hence the name Atari Punk Console.
This is a dual Eurorack version, 10 HP, so two APC's in one module. You can modulate one with the output of the other. The cat eyes light up according to the intensity of the output.
