BackBoards. Final work on PCB with exploratory 8hp layout 0d370a24cdcaf6d3fd7f0316855522b79df0fe9a 3583986e89 Finished PCB, passes all passable DRCs created pull request synth_mages/MK_VCO#2 merged pull request synth_mages/MK_SEQ#2 Added schmancy pcb for v1 build - C1 is too small for film; is film needed? More notes Schematics/schematic_bugs_v1.txt | 2 Smaller cap (476nF?) for C1 Ceramic 104s for C10, C14, might be fine, might introduce intermittents - Don't put R8 so close to R26 -- D36/R47 too close Testing before powering up: Clock In Normal - 1k to U2-8 (AND NOT short to U2-10 Clock Rate - variable resist +6k between U2-8 and U2-9 Reset Sw - when pressed, short +12V and Reset In - diode to U2-3 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 - Single Step - 12V through 10k Ohms to U-1-14, more like 1M when off - Glide attenuator (B10k) (join two left pins from below Pots.
