I'm not sure how relevant it is, but I've been able to do this with a IIsi. I don't have a way to use it anymore though, my screen went walkabouts. The modification was a simple matter if wiring an ATX extension loom to the psu socket, making sure voltages matched. It could be worth trying for yourself.

Yup. It was here. It's a very sophisticated paperclip but also the proof of concept that the ATX PSU can be soft-controlled by the IIsi... it's just a matter of placing an inverter between the /PFW line from the Mac and the /PS_ON input of the PSU -- they work just the opposite.Trash80toHP_Mini wrote:ISTR someone, (Zuiko or ojfd?) posting a pic showing him using a paperclip as a momentary switch between the two lines you need to wire up for soft power. It's in this thread, one of the linked threads, or I've got it in my War Room links list, IIRC. I'll give it a look.
