Hello
This is my auction you are talking about
I have a GRex up for sale but the GRex was never used with this
mainboard or with the PPC card I offer at the moment.
The molex connector is connected to the mainboard and graps
+12V, ground,ground and +5 Volt. This is what you need at the
floppy connector on the mainboard. If you bridge it you have a better
Voltage on a installed Blizzard PPC card ! I measured the voltage with
and without the bridged wire. The result is about 0.3 Volts more with
the wire ! There is no -12 Volt wire.
Update: The 4 wires with the molex connector are only for internal use to give a ppc card a better voltage (through the Floppy connector) !
The Amiga gets its power with a total normal PSU ( in my case the psu is a bit more powerful but it has the normal Amiga power connector)
