Just wanted a little more into how this circuit outputs 14VDC after the 7809. Am I correct in the assumption that the 7809 sums the +9VDC and the +5VDC to create a +14VDC output? I'm using my SID not only to add a synth to my growing studio but to also understand electronic design a little bit better.

Nevermind read the walkthrough closly again. I can use this for one SID. Enjoy the switches ;). Oh I am also blogging about my progress for anyone who wants to take a look. www.frishkorn.net.

I also need help with a PSU question but I also have two things to offer. Can I still use the optimized psu with a single sid solution? Still doing exactly was it say i.e. remove IC3 from the core? You can order the same switch from digikey. It's from NKK Switches. Visit there site and figure out the solution that will work best for your midibox SID. The one i'll be using is the M2022TXG41-DA-RO. Here are the links. http://dkc3.digikey.com/PDF/T073/1873-1874.pdf and http://www.nkkswitches.com/pdf/M2rockers.pdf. Also the PSU connector is just your old fashioned DIN 7 pin. Which can be also ordered from digikey. http://parts.digikey.com/1/parts/264966-conn-din-7-pin-female-pcb-sds70j.html.
