Unescape threeUHeight = 133.35; // overall 3u height panelOuterHeight =128.5; panelInnerHeight = 110; // rail clearance issues, make all power traces large Added input resistor for sync; placed everything on PCB choices could also be made available under CC0 may be necessary to make fitting inside a case easier. Or 10mm if it can fit; losing the bodge area. Don't put R8 so close to R26 D36/R47 too close Testing before powering up: Clock In - ~27K to U3-8? No, transistors maybe activate? - Clock rate goes down when resistance goes up, opposite to expectation.
