"This is a bizarre little LFO that produces a wide range of pseudo random effects.
The circuit consists of several distinct blocks. The first is the collection of square wave oscillators, three of which run at fixed though different frequencies. The fourth is variable between much slower than the others to much faster than the others. These oscillators are all based on single schmitt trigger stages of a CMOS 74C14, 40106 or similar."

"This is a great find for those who enjoy building custom modules. these are increasingly harder to find. especially with all the boards together w/ their respective ROMs, let alone two full sets.

These are both the version 3 board without the 2532 error on them."
