Chassis Jacks: J1 - Mini-DIN-6 Female Chassis Connector J2 - USB-B Chassis Jack Configuration Headers / Jumpers: These headers are installed so the shorter section is inserted (soldered) into the board JU1 - 3 pin header - green - with shorting bar or "shunt" JU2 - 3 pin header - yellow - with shorting bar or "shunt" JU3 - 2 pin header - blue - with shorting bar or "shunt" JU4 - 3-pin header - blue - with shorting bar or "shunt" JU5 - 3 pin header - blue - with shorting bar or "shunt" JU6 - 2 pin header - red - with shorting bar or "shunt" JU7 - 3 pin header - blue - with shorting bar or "shunt" JU8 - 2 pin header - blue - with shorting bar or "shunt" JU9 - 2 pin header - blue - with shorting bar or "shunt" These headers are installed so the shorter section is inserted (soldered) into the board H1 - 4 pin header - white - with jumper H2 - 4 pin header - white - with jumper LEDs: Install absolutely last! LED1 - 3mm Red LED - with short lens to match the length of LED2/3. LED2/3 - multi-color (amber/yellow/green) with clear lens. (Location LED3) The Red LED orients with the short lead in the square hole. The multi-color LED orients with the shortest lead in the square hole. Bend the leads to match the ones on the original circuit board. Use the front panel (by itself) sliding it over the shaft pots and power switch to align the LEDs while soldering in place. IC Sockets: (3) 8 Pin DIP IC Sockets - Note orientation notch - match with silkscreen. Crystal: Y1 - 12 MHz Crystal - When installing - use supplied plastic spacer, and install tight against board.

Don't try to pull the component away from the carrier paper otherwise you could damage it. NOTE: Some components have pre-bent leads and they'll need to be reformed to allow the part to fully seat on the surface of the circuit board. NOTE: Polarized capacitor locations include a + (plus sign) silkscreened on the board where the positive lead orients. NOTE: Some capacitors have marking on both sides. The marking on one side may not be the value. Turn the component over and read both sides to determine its value. Capacitors: C1 - 47pF small yellow MLCC (marked 47 or 470) C2 - 20pF or 22pF yellow or blue MLCC (marked 20, 200 or 22, 220) C3 - .47uF Tantalum (blue) (observe polarity!) (See below for installation note) C4 - 20pF or 22pF yellow or blue MLCC (marked 20, 200 or 22, 220) C5 - .47uF Tantalum (blue) (observe polarity!) (See below for installation note) C3 and C5 installation note: The positive lead is on the right side when the printing is facing you. C3 is installed so its printing faces C2. C5 is installed so its printing faces AWAY FROM C4. C6 - 10uF electrolytic (observe polarity!) C7 - 10uF electrolytic (observe polarity!) C8 - 10uF electrolytic (observe polarity!)
