If only! That question has been asked many times on SGI forums like nekochan, for the Sony PSU (like this one) and also the Nidec. No-one has ever claimed to have seen one, and the chances are Sony wouldn't ever have released them.
Yea I was looking for the Nidec one for the Indigo, as mine constantly spits out a power lost error on the console of my R4000. IIRC Nidec said no, but Sony might be different. I think there is a private system that Sony repair shops can access that has schematics online.
I have thought about tracing out the relevant area of the circuit, but it would take a while as the components are fairly densely packed, and I've got several other tasks on the agenda.
I can imagine that would take a ton of time. And the parts list still wouldn't be official.
