Part of a white noise generator that employs a string of MAR-6s to "oomph" the output a bit. This small project was a complete failure as the MAR-6s got into self-oscillation straight after power-up, and while it produced a lot of noise, it wasn't exactly uniform.
I have published some source code for various small hobby projects at github. Take a look at my profile for an overview. There could also be some stuff in the download directory.
