Linchpin your one crazy dude....
Easiest way to power the 1200 is:
From the PC power supply connect a the small Floppy power connecter to the floppy power supply header on the A1200. Then find -12V on the PC PSU (usually blue wire) and stick this into the Amiga 1200 Power connector centre hole.
If you are gonna hang a lot of stuff of the mobo, Clock port gadgets, 2.5" Hard disc Accelerator, then chop the lead of the A1200 power supply about 6" from the block. strip back the wires on the A1200 power supply, measure the voltages from the wires:
I think its...... but check first as its been a while....
Black - GND
Red +5V
Brown +12V
White -12V
Then Shield Ground.
Match these up with the PC voltages and join the lead up you chopped off.
To power up an ATX PSU with out it being attached to a PC either join the green wire to the black wire next to it and use the switch on the back of the PSU or put a switch between the wires
