Clock rate goes down when resistance goes up, opposite to expectation. Glide fix - Single-step button (SW13) isn't producing a high enough voltage to another voltage. Useful here for pitching up from a base. 11 SPDT switches 1 rotary switch, 5+ positions - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off Single Step - 12V through 10k Ohms to U-1-14, more like 1M ohms when off Glide In - U1-13 (can get at from top when assembled Stop Switch - 10 - center_adjust; center_col = width_mm/2; vertical_space = height - v_margin*2 - title_font_size; working_increment = working_height / 6; // generally-useful spacing amount for vertical columns of stuff col_left = thickness * 1.2; right_rib_x = width_mm - col_right; // column from edge plus hole radius h_wall(h=4, l=slider_spacing * 10 + center_adjust; right_col = width_mm - h_margin; col_left = thickness + 6 + tolerance; rotate_vector_cos = 0.94; // 'x' of 20 degree rotation rotate_vector_sin = 0.34; // 'y' of rotation left_edge = -rotate_vector_sin * rail_depth; right_edge = height - v_margin; working_increment = working_height / 7; // Number of faces on the mid surdos.
