So like you could make leopard run on a G3? :)
well you can run Leopard on a G3 system that has a G4 upgrade on it, but its not the same as running it on a G3 tho since it has a G4 CPU.

I got bored, so I decided to give my Power Mac G4 Quicksilver a little boost. Removed the CPU module and flipped it over. Then I whipped out the soldering iron.

Keep in mind I had no idea how to microsolder. I heated the small pads on either side of resistor R3 and flicked it off with a fine tip knife.

Dropped it back in the system. Nothing happened, no chime, no life. Here's two tips for you all. ALWAYS have the CPU screwed into place, one of those screws connects the CPU to the case and acts as a 12v line. Without it, you won't get a chime. The second tip is ALWAYS have the heatsink on, even if you intend to only quickly test the system. Saves you a lot of hassle with kernel panics.

Tightened the screws, replaced the heatsink and started it up into Mac OS X Leopard.

"800mhz PowerPC G4"

It's quite a minor increase when you look at it. It was a 733mhz CPU now clocked up to an 800mhz and absolutely loving it. No stability issues whatsoever even after some endurance testing.

While I was in there, I also used cable ties to bunch up some of the wiring in the bottom of the case. Looks good in there now, the door opens and closes easily and the cables don't flap around now they're securely fastened.

The AOpen PSU is also finally fitted and working fantastic with the machine, although i'm not sure i'll keep this one in due to the fact the Auriga one is a little better. We'll see eventually.

I finally got around to looking at some of those. The first link is what we're already trying to accomplish. The second is what we previously tried to do but turned out to be less than ideal... the third is quite confusing but I can see what he's trying to do, feed the 5v trickle power directly to the front panel for the system starter. The final is an interesting one I may try at a later date.

Now all this needs to get flying is the secondary 24v power supply, hard disk and DVD recorder (both of the latter are currently in the eMac). Another 512mb SDRAM stick may be on the cards to bring it up to a total RAM count of 1GB.

All in all the project is coming along quite nicely.

PS. Here's the updated version of the wiring diagram. I've made a few alterations to clarify just where to bridge the wires, otherwise all the wires are the same.

I tore down the eMac for the vital parts last night, hard disk, RAM and optical drive. Of course I made sure the eMac was still functional by refitting a smaller 40gb HD and CDROM with 384mb RAM.

As a result though, the Quicksilver was placed into active service.

Quicksilver in Action

The setup is still bulky and the desk does need a tidy up. An LCD panel would really set this machine off.

After the fitting of new parts I test started it. No chime. Turned out to be the 12v positive feed to the CPU module, the pin had come loose of the molex connector.

Test start 2, this time it chimed and started up to... not quite ideal conditions. One of the wires inside the case, an ATX 3.3v feed had split and was only just touching against the pin, brushing it. Opened it up and cut the 3.3v line out, it wasn't exactly needed in this configuration.

Third time lucky? Yes. Fired right up smoothly and went into an 8 hour run cycle to ensure this machine was reliable. Tests included an hours idle, then some normal use, some heavy use, then power tests (sleep mode, etc) before throwing it back into another idle test cycle. Very stable, very fast and very spiffy.

From a doorstop in the IT administrators office to a fully working 800mhz "Supercharged" G4. The Phoenix has well and truly been reborn.

SYSTEM
Macintosh Server G4 "Quicksilver"

- 800mhz PowerPC G4 (from 733)

- 768mb PC133 SDRAM

- 32mb nVidia GeForce2 MX

- 160gb HDD

- LG SuperMulti 32x DVD-RW

- Mac OS X 10.4.11

- Belkin 3-Port USB 2.0 Card

- NEC 4-Port FireWire 400 Card

- Laser Internal Bluetooth Adapter

- AOpen 250w ATX PSU

- 19v Secondary PSU

FUTURE (???)

- 1GB PC133 SDRAM

- 240GB Storage (160+80)

- Mac OS X 10.5.4

- 24v Secondary PSU
The system is most certainly capable of Mac OS X Leopard from the week long test run I held last week.

Imagine BootX even whipped up a custom boot screen for it.
