[sdiy] Moog Memorymoog clone almost completed

[Luís Marka]

I can prepare a package with all Kicad files for boards, as well as the 
Autocad drawings for the case, metal and wood parts, and send it to 
anyone interested. Still need to find a way to get the buttons done, my 
attempts have not been successful so far.

Obviously it uses a LOT of parts...

Cheers!
