Yamaha CS80

Well, thanks to Bradley/Synth80s (and my friend Ed, for helping me 
get it up the stairs), I am once again a CS-80 owner!  The tolex is 
a little bit rough and the keyboard needs a bit of work, but the 
panel/knobs look and work great and the tuning is perfect.  

Now I have to decide how much restoration and/or modification I want 
to do to it.  At the minimum I'll fix up the keyboard, clean up some 
cosmetics, and add Crow's fixes to the CMOS boards (bypass caps, 
etc).

At the other extreme is to gut all electronics between the 
knobs/keyboard and the voice cards, replacing it all with a CPU/FPGA 
based board to have MIDI, CV/Gate I/O, programmable presets (like 
Prophet 5/OBX), voice assignment/unision modes, multi-timbral, auto-
tune, and split into two (three with power supply?) cabinets so one 
person can move it.

I'm an electrical engineer and have some woodworking skills 
(including portabilizing a couple of Hammond organs), so it's all 
possible if I have the time and energy.

I'm going to take quite some time planning, deciding, and just 
playing, before I do anything drastic.  I'll be running some of 
these ideas in detail in the mods thread, but if there are other 
CS80 owners interested in massive rebuilds/mods, let me know, 
especially if you have engineering, firmware, or cabinet-making 
skills (hi Crow & Kent!).  It would great to come up with a common 
set of mods and split the development effort.

Much more later,

 David
