Firstly we need the a P5 molex (same as the one for the floppy drive) from the PSU, this will plug into the A1200 motherboard where the floppy power once was.
Secondly, we need to complete the circuit with the -12v (thats the blue wire in the ATX or white in the AT) please check voltages before use!!!!
once you found it, you will need to feed this into the central hole of the a1200 power connector, i would suggest you "tin" the wire but a good few twists in a solid build will do the job.
if thats a little hairy, i shall add some pics for you.
