Eml synthesizers

I've auctioned those modules (at least most of them), so my questions
start:

a) on the (incomplete) ADSR i see 3 x IC's missing, only one the board
with LF356J. Board is labeled EML ADSR 9-76. 3 Pots 1 MEG Ohm, 1 Pot
5KOhms. Do we have any schematics for those? And it's EML100/400 or 500? 
b) What is the power level for those modules ? 12V ? 15V ? 9V ?
c) The VCO PCB is labeled EML VCO 12-76
d) On the NOISE PCB there are 2 IC's missing. Board is labeled EML 05
8-77. Schematics ?
e) The VCA's are labeled EML400-6 2/77. Fully equipped. I assume this
is a EML400 board ... any Schematics ?

Any help appreciated.
