   - JD1, JD2, JD3, JD4, JD5, JD6, JD7, JD8, JD9 are pads to connect to a control surface. If using the MB-6582 control surface PCB in a PT-10 case (or similar sized case), do not solder SIL headers to these pads, the connection to the control surface PCB is via ribbon cables soldered directly to the pads. Refer to MB-6582 Control Surface Construction Guide.   - JD1, JD2, JD3, JD4, JD5, JD6, JD7, JD8, JD9 are pads to connect to a control surface.

   - The switch S1 is the same switch as found in a Commodore 64. You can temporarily use any DPDT switch until a good supply of these switches is located. **The DPDT rocker switch from Mountain Switches which was previously suggested ([[http://​www.mouser.com/​catalog/​specsheets/​MS-100818.pdf]]) does not suit the rearpanel design.**   - The switch S1 is the same switch as found in a Commodore 64.

-  - These capacitors on the SID control the filter cutoff frequency. For 6581, they should be 470pF. For 8580/6582, they should be 22nF. To allow for interchangeable capacitors (should you wish to swap between 6581 and 8580/6582), solder a strip of 6 machine pins (available from [[http://​uk.farnell.com/​jsp/​search/​productdetail.jsp?​CMP=i-ddd7-00001003&​sku=1023035|Farnell]] ​and [[http://​www.mouser.com/​ProductDetail/​Harwin/​D01-9973242/?​qs=ecHgFjcWJS%252bVNM5C80XwDA%3d%3d|Mouser]] into the pads for these capacitors. Alternately,​ cut up an IC socket. Even if you plan to only use one type of SID, not soldering the capacitors gives you the opportunity to tweak the capacitors, install better ones later, etc.+  - These capacitors on the SID control the filter cutoff frequency.

   - If using PSU Option B, 3-pin SIL headers in these pads allow switching the voltage supply to the SID between +9v and +12v. Use a jumper (shunt). If using PSU Option A, bridge between middle pin and "​9V"​ pin with a resistor lead.   - If using PSU Option B, 3-pin SIL headers in these pads allow switching the voltage supply to the SID between +9v and +12v.

   - These are the SID's audio input and output headers, which can be used to connect feedback pots (like on the rear panel of MB-6582). If not using (or until you connect) feedback pots, use a jumper (shunt) between "​IN"​ and "​GND"​ pins. You can also use these headers to connect audio sockets for external audio input to the SID (but preferably sockets with switch so unused socket will ground the input).   - These are the SID's audio input and output headers, which can be used to connect feedback pots (like on the rear panel of MB-6582).
