Atari Video Music C-240 with Lars Larsen (LZX Switched On) Mods


via this auction

"The original Atari C-240 Video Music device is rare, and here is an even rarer unit with modifications by Lars Larsen from LZX Industries! Switched On, the synthesizer store in Austin had Larsen modding c240s for a brief time in 2010 and 2011 before Larsen moved on and started LZX.

The some modifications that make this unit 1000x more handy than an original:
Replaced the terrible flimsy wall wart power supply with a new standard 3 prong
Replaced the coaxial output that required RF demodulation to be usable with a standard component (yellow rca) out
Replaced the rca audio input with standard 1/4" input
The other modifications are a bit more esoteric:
Extra Inputs
Atari Fuzz Chip output
Knobs and switches to control video grids
Someone else wrote all this stuff up and provided a youtube link, and the description is proper:
'This is a limited edition video music modified by Switched On Music Electronics in Austin Texas. Switched On modified 10 of these last year, adding a composite video output (NTSC), 1/4" audio inputs and outputs, a fuzz output (audio from the Atari's built-in distortion circuit=insane FUZZ), and waveform mixer controls for the comparator. With the mods, the Video Music can function as a video synthesizer with no audio input at all--this gives you quite a bit of control over color and shape. It is difficult to achieve this sort of functionality without spending thousands on new LZX system.'"
