Original README: * LEDs in many places might be fine, might introduce intermittents - Don't put R8 so close to R26 -- D36/R47 too close Testing before powering up: Clock In - U1-13 (can get at from top when assembled Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M when off - Single Step - 12V through 10k Ohms to U-1-14, more like 1M ohms when off Single Step - 12V through 10k Ohms to U-1-14, more like 1M when off Glide In - ~27K to U3-8? No, transistors maybe activate? - Clock Rate - variable resist +6k between U2-8 and U2-9 - Reset Socket to U3-3 = capacitor measurement roughly 15nF (has a resistor limiting max drone frequency:
