Yeah, someone answered that question for me in another thread of mine. Thanks for answering my question though!
Yeah, pretty much.

Forgot to add that it's mainly useful in server-type environments where you want it to reboot automatically after a power outage (this was before smarter ATX-like power supplies and computers (Mac and PC alike) could do this via software).
I don't know this, but can the early Power Macs do this via software? I know later ones can (the feature was certainly around by the time the G3-based Power Macs came about). I'm talking desktops here; PowerBooks probably had the feature a bit earlier (very early on, most kinds of more advanced power management, such as the Sleep command, were pretty much exclusive to the PowerBooks).

Good news! I have recapped the logic board and partially recapped the PSU (turns out I forgot to order a few caps :/ Got all the bad leakers changed though). But the machine actually fires up and chimes now! I haven’t plugged in a monitor yet, but I’ll do that soon.
At first it came on for about 10 seconds and then shutoff. Then after that it would only come on for about 1 second before shutting off. And then (after a few more times of unplugging it/plugging it back in) it got to where it would power up fine but couldn’t shut off! So I pulled that little soft power control board (I think that’s what it is anyways) back out, resoldered some things on it and all is good now! It turns on and off just like it should!
This is is the first logic board I have ever recapped with polymer caps. I love the fact that they look almost just like the originals but are solid state! I found them to be a little harder to install than tantalums (my usual choice for logic boards), but they weren’t too bad.
I also have included a pic of the soft power control board from the PSU (this was after I had removed the caps from it). Look how nasty that thing was! There actually wasn’t any broken traces though! It was just the solder mask that had gotten damaged.
