The Powermac G3, apple's G3 Powerhouse. This computer Introduced the design that stuck until the powermac G5, but this computer started the "Handle's" Trend, every powermac G3, G4, G5, and Mac Pro now has handles. This computer boasted a 350Mhz, 400Mhz, and 450Mhz PowerPC G3 CPU. This cpu is incredibly easy to overclock, due to it's "clock-config" jumper convienlently located next to the CPU(though i don't encourage overclocking). This computer had blue plastic, resembelent of the iMac G3's and the iBook G3 Clamshells. It would have been great if Apple had made this is other colors, like the imac, a lime green Powermac G3 would rock!

Removing The CPU Start by using a flathead to gently pry off the clip, remember you have to put it back on again! Then, remove the heatsink.

Then, lift the metal retaining lever. Then, lift the CPU out of it's socket. This is the Motorola MPC106 PCI bridge and memory controller.

  • Once that's done, pull the card out.

  • Sorry Guys, Regular PCI Cards Won't work here, only Mac Edition PCI-Compatible Cards, and this card won't work in a PC, Also, graphics cards only work in the first slot, the other 4 PCI Slots won't support graphics cards.

Then remove this screw too. Then lift the module out, there is a connector underneath it, to be careful while doing this. Then we can move on.

This will reveal 2 phillips screws. Remove them. Then push the back of the cage out the front of the case far enough to remove the ribbon and power cables, than slide the cage completly out, and set it aside.

Removing the power supply Disconnect the power connector from the logic board (this looks alot like a standard ATX connector. The lone difference is that the wire which supplies -5V on an ATX supply [pin 18] becomes a ground wire in the B&W G3.  If you just plug in an ATX supply without any modifications, you'll short out its -5V output. ) There is a 4-Pin Cable connected to the front panel box, remove it.

  • Remove these phillips screws.

  • Now, you can slide the power supply towards you, and remove it.

  • Sorry, but my camera battery died, I will post photos on how to remove the logic board after I take them

Sorry, but you didn’t mention to remove 2 hex screws from the back of the case on both sides of the power connectors!

  • Also remove all 3 hex screws from the rear of the case located around the power connectors. Only then, will the PS "just slide out."

The CPU socket looks identical to Intel's socket 478.

Actually, I have to call you on your comment about the PCI slots. I used to run a dual monitor setup on my B&W G3. I had an ATI Xclaim VR 128 installed in the second slot, giving me a second graphics card, with a TV tuner/AV input. It worked perfectly. The Tuner's software never made the transition to Mac OS X, sadly, so i had to boot into OS 9 any time I wanted to do recording, but it most definitely worked.

Yep, the pci slots will absolutely run graphics cards. If they didn't they wouldn't be pci slots. I also ran graphics cards off of them. However, they run like crud compared to the 66mhz slot, since they are shared and 33mhz. You can also run standard PC graphics cards, as long as there is a mac compatible rom that you can flash onto it. Reflashed cards used to sell on ebay for real good prices.
