The eagle files are the main thing I have, plus some conversations
already on sdiy and a bit of one-on-one emails. I'll try to write up
the various things I know and submit it to the list.

Yeah, I already have a mcv628 that I am using right now, though it
require +-15v  so I can't mount it internally. I've seen this:
http://www.midi-hardware.com/midimplant, plus a few others, that look
nice, but I 'm seriously thinking of designing my own with an arduino
and a DAC; once I get the oscillator board up and running I can throw
together a prototype.

Are you talking about links on the page or my page itself? I haven't
had problems in the past, though I don't use it that often so I may
have missed downtime in the past.
