I can boot her up now with the antec if I do a very fast doubleswitching of the powerswitch.
I removed the pin off the powerconnector and rubbed it clean(little brownish) and made the pin a little wider.
I also soldered a few wires to the zorro connector(+5V and a gnd).
Still there is no more then 4.87V which isn,t enough to keep the delfina going or warpos.
Best would be to solder the wires of an other connector on the underside of the mobo directly?
Could use some thick wires and a few AMP connectors.
Would the mediator be happy with only +5V and a GND or should it also need a 12V line?
Still strange that I have to doublestart to boot(only with the ppc not with "normal" processorcard.
Hoping to find the cure for this!
