I want to adapt an AT style pc power supply to power my 1200. there are 5 pins on the 1200 power supply...
PIN---- NAME
1------ +5v
2------ shield ground
3------ +12v
4------ signal ground
5------ -12v
1,3,5 are self explanatory, but I don't get 2 and 4. is there something special about these grounds? does anyone know what the corresponding pins on the AT PSU are?
Thanks,
AL
