Hi there Mr. Dibbler :)
Nice little project!
You should really consider losing the SMD-fear. I don't see a ton of "omg I just can't solder the gm5" around here after about two metric f*ckloads having been sold and soldered ;)
That's not sad, that's smart. Blue LEDs are teh evil. They hurt your eyes, have a tendency to be way too bright anyways, ... Dig around the forum for more reasons ;)
If you are ankage or michael123 get in touch with me NOW or you'll be dropped from the list.

We're not doing the whole "offer collecting, bidding the price up" kinda thing around here. As the seller, please name a reasonable price (ie parts cost).
0.5Ohms between +12V and ground is bad. There's a short somewhere. I guess this is where you quintuple check every solder joint and then start to remove parts until the short is gone. I'd start removing the 7809 as it's a central point in the PSU part.
Are you pouting now? Seriously? :rolleyes:

Sorry for that unwelcoming Welcome. We are usually a nice bunch. But posts can get overlooked. I for instance missed this post until you replied to it. And now I really don't feel like typing up a wordy response explaining stuff you can find by yourself.
You're well in the "a few grand" range with that. A rough guesstimate with the numbers you've given says you'll be looking at 8-15k EUR. With a guesstimated build time of ~500 hours of soldering + about the same again for wiring and the case.
For a loopback test try looping the midi device only to see if it correctly sends out sysex. If that works you can try what you described (it won't blow up anything). If that doesn't work, check the parts around the MIDI in (resistors, optocoupler mounted the right way around)...
Neither. The CS pin is just the "chip select" pin, that enables/disables data IO to the SID. It doesn't enable disable any part of the SID in particular. See: http://en.wikipedia.org/wiki/Chip_Select
Long story short: That pin doesn't have anything to do with what you want to do.
