    I don't believe that my AT supply has 3.3v. (desktop supply that is) I will check when i get home, as im at uni now, but I'm 95% sure that it only has +/- 5 and +/-12 volts

      Yeah I know, my at deskop supply doesnt have it either. But what is it for? I built my sproggy with the 5volt and the 3.3 volt, but I cant figur out what this is needed for. I may as well use 2X 5volt ic's and doublt the 5volt current.
      My motherboard has both at and atx connectors. may as well use the AT one.
