| Though a single power supply may work, the voltage needs to be high enough to supply the regulator on your SID board. Because of the higher input voltage, the 5V (7805) regulators on your CORE module(s) will get very hot, especially if you are powering a backlit LCD. | Though a single power supply may work, the voltage needs to be high enough to supply the regulator on your SID board.

| + | For powering 2core with 2 sid 8580 with a complete (Step C) control surface a 1A/12V power supply should be sufficient sufficient. you can buy 7805 and 7809 regulator that supports up to 1A and chain them togheter (the PSU connectet to the 7809 and the 7805 connected to the 7809 output). | ||

| Thanks wilba for the tip, you can remove everything to the left of the regulator including the regulator shown on the multi sid PDF. Remember to bridge the core PCB's where the regulators used to be. I have also heard of swapping the 2200uf cap, and not including the bridge on the cores too but I have not tested it (dcer10). Also remember when you are testing the multi sid that you need to press the link button to hear the extra sids! | Thanks wilba for the tip, you can remove everything to the left of the regulator including the regulator shown on the multi sid PDF.

| + | ===== How do I connect the SID-module to the Core-module ===== | ||
| + | |||
| + | This question has been asked many times in the forum. | ||
| + | The pins don't all match name for name, that's the confusing bit! The pins to connect will be in the same position on those 2x5 headers. | ||
| + | It should be a 1:1 connection: | ||
| + | |||
| + | |Core:J10| SID:J2| | ||
| + | |Vd| Vc| | ||
| + | |Vs| Vs| | ||
| + | |CLK| CLK| | ||
| + | |SC| --| | ||
| + | |MU| MU| | ||
| + | |RC| RC| | ||
| + | |MD| SC| | ||
| + | |SO| SO| | ||
| + | |--| --| | ||
| + | |--| --| | ||
| + | |||
| + | To avoid ground loops, it is recommended to use Vd and Vs from J2 of the Core module instead of J10. | ||
