Forrest M. Mimms III "Step Tone Generator" AKA "Atari Punk Console" with 4 Step Sequencer Retro Fit into a Cathode Ray Tube Tester Case.

I built this original circuit from two 555 timer chips at the heart of the "Atari Punk Console". A 4017 decade counter and a 4049 clock chip control the 4 step sequence. 4 LEDS, three retro-fit into the face plate, the fourth within the case. The circuit is retro-fit into a vintage Cathode Ray Tube Tester case by BK. Case is grungy, like sound,

The smallest knob on the lower left controls the clock speed. Four large knobs at bottom control pitch of individual notes in the sequence. The two large knobs in the blue field control the frequency and duty cycle of the step tone generator. There is a spring loaded hold switch at the lower right that stops the sequencer, allowing adjustment of individual "notes".

Please watch this video for a brief demonstration:
