The Harvestman – Zorlon Cannon

via this auction
"Overview:
Voltage-controlled pseudorandom pulse and pitched noise generator.
The design of this module was inspired by the logically economical and timbrally memorable sound generation method of Atari's 8-bit computers, also found on their 2600 and 5200 series video game systems.
The upper section is a clock generator with four pseudo-random gate outputs that are derived for mthe master clock, which is perfect for random triggering of envelopes etc. The bottom section is a generator of tunable digital noise with different timbres, suitable for noise melodies. Or use it as a crunchy digital oscillator.

Technical details:
upper section: Manual and Voltage Controlled master clock frequency and seed value (periodicity). Gate voltage levels: off = 0V, on = +12V bottom section: The four parallel audio outputs operate with similar spectral behavior and a much-improved frequency resolution. This section of the module offers several different flavors of pitched audio noise with varying degrees of periodicity. Toggle switches are available for changing the behavior of each output, from more noisy behavior to a pure square wave. Manual and voltage control of the audio frequency is available.
+/-12V Doepfer-style power connector 5V power supply encouraged. Onboard regulator available otherwise, 5V power source selectable by jumper.

Inputs and outputs:
upper section: Clock output, 4x random pulse outputs, Frequency CV input, periodicity CV input
bottom section: 4x pitched noise outputs (4, 5, 17, and 9 bit sequences), audio frequency CV input

Measures and weight:
3U eurorack module / width: 11HP (yes, eleven!) / depth (from back of faceplate) 33mm / current draw: ?? / weight ca.170g"
