Emax

Hi Davide,
In fact i did just one common connector on the ATX psu to deliver power 
: It's the -12V.
For the others voltage i've choose each time a separate power wire from 
the PSU ...
So, the common -12V from the ATX PSU seems powered enough for the Emax :)
Hope your Emax will rebirth for long years ! ;-)
