MOTM

I have, sitting in front of me, two Emu 4000 monophonic keyboards and one Emu 
4060 keyboard/sequencer (unfortunately without the output panel that goes in 
the module rack).  The two 4000's do not have a modulation input and control 
that are standard, but otherwise look fairly stock.  They are all pretty beat 
up, but I am hoping to get at least one of the 4000's working for my own use. 
 All of these were formerly from Frank Zappa's studio, so they hold a 
particular sentimental value for me as well.

Anyway, I have the basic information on these modules but no service 
information or schematics.  Does anyone out there know a source for this 
information?  I've got a call in to Emu but they don't seem to hopeful about 
still having this info.
