One more panel i'll never build most likely , inspired by Modern Implement Company page at the old Grant Richter's website ,this is 12 modules cramped together on a small panel ,4 x S&H's ,Slope detector ,CV Processor ,Noise and Random Gates ,2 x Compaarators ,2 x Gated Slews ..since it's 4 x S&H's the idea was to use Osamu Hoshuyama's Toy Sample and Holds using CD4007UB
