O_O WTF... Macintosh G3 have Socket A?! (Excuse me if I'm wrong, because I only have worked on G5 one.)

And if it DOES have Socket A, then Sonata have found her match with Athlon XP-kun! XD

And I have done MacOS9 emulation, it wasn't too difficult for AMD CPU - ran it on both Athlon 64 and x86 Cell, with a custom firmware - booted up fine.

It may be a bit hard on Intel CPU, because MacOS dislike CISC processor, and the CPU mentioned above, are RISC.

Eeeehm, no... Well, yes and no...
Although it has a Socket A, i guess that it stands for Socket Apple or something, you know, to confuse PC users... It has Third Generation PowerPC Chip...

Here's some pics, btw...

I got her to work by the way... Aparently the previous owner was very sloppy, or couldn't get her to work again, because now i can delete all his personal files... (well except for the music, i'm keeping that ^_^)

But i'm happy that i got her to work (without crashing in 10 seconds to 3 minutes ^_^)... Took me a while, needed to replace a dimm, rejumper the harddrive, and remove the PCI NIC, wich was unneccesary anyway, since the Mac has a built in 10/100base tx lan port...

I am pleasantly surprised by the onboard speaker, btw... produces nicer sound than those onboard PC-speakers (not hard to accomplish)... And a bit less pleasantly surprised by the sheer weight of the thing... 27 pounds! (13Kg!!), wtf did they do to get it so heavy?!

Dr. Mario · March 31, 2009, 11:18:45 AM

Well, thank for correcting me... ^_^;
Nice motherboard! That's good that You got her to boot up, now that she's usable.

Also, it looks like you can use Athlon XP cooling fan on G3 daugther card - just be careful about the fan clip, though. (you can use original heatsink clip.)

Now, my buddy, why is your Macintosh case heavy? It's made of Japanese cold-roll steel. I have PC case that's made of the same material, it's heavy, but pretty durable. It took few beatings already and the innards are fine.

Smokey · March 31, 2009, 03:31:27 PM

Ah, right... I like my cases durable, so that's another plus for my Mac...
BTW, i am currently typing this on my mac (wich runs OSX 10.3.9 pretty smoothly), I have decided that i would give my PC a break and hook my Keyboard, wireless mouse (Microsoft of all brands ^_^) and TFT screen to the Mac, wich works pretty fine, although i have to get used to the fact that what used to be [ctrl] on my windows machine is now [windows key] on the mac... ^_^
Also i achieved major stability improvement by replacing the 80wire rounded ATA cable by an old-fashioned 40wire flat one... (never hurts to keep some of the old stuff, i even got SIMM 32 and SIMM72s ^_^)

God i have to say it is really quiet now in my room... ;010

DAMN YOU SMOKEY
DAMN YOU

Smokey · March 31, 2009, 05:04:17 PM

Hehe, i had to cool my other PC with 3 120mm fans, 2 80mm fans and a 240mm fan... so yeah it is very serene now that i gave my PC a break...

Dr. Mario · April 01, 2009, 12:34:35 AM

:smoke: At least I don't have to complain at all, because I'm already deaf.

But if I decide to use my CI, I could hear my computer, because it has two of Sunon's powerful 80mm fans, the one that kind of look like a turbofan engine - one to suck cold air in, another to blow on a modified AMD Phenom retail heatpiped heatsink. When my mobo decides it need more air, it will start to really sound like a turbofan engine accelerating.

Oh well, it's better than having toasted CPU.

Added after 25 minutes:

Okay, pulled the picture of a rather powerful fan off goldmine-elec.com - My PC has two of 'em, exactly the same as what's in this picture.

;013 Srsly, WTF... I've been trying to get my PC to sound like a Pratt & Whitney Turbofan for ages... I likes the sound of a turbofan starting up , so....Sounds like power.... ^_^

Dr. Mario · April 01, 2009, 10:25:24 AM

This fan does... That was why I had to plug it in aside the voltage regulators on the board so no one would complain. Be warned, though, this fan makes loud whooshing sound. If you like the sound of P&W Turbofan engine, this one is definitely the one to experiment with. Also, this fan that size (80mm) blows a gale wind at full voltage (at 12 Volts DC).

Smokey · April 01, 2009, 01:01:59 PM

Heh, heh, heh... I will hunt two of those down and put them in my case... ;006

Dr. Mario · April 01, 2009, 03:20:43 PM

Here's a hint that will make your hunt a bit easier: Go for Vantec Tornado 80mm Case Fan. I got this fan this way.

Also, best of all, It contains two ball bearings, which this fan will last a long time.

Smokey · April 01, 2009, 03:41:28 PM

Ah, nice... i really have come to hate those sleeve bearings... they get noisy the wrong way...
Man when i'm through with this system it's going to be the noisiest in town... Maybe i should go for liquid cooling to add more fans...

Dr. Mario · April 01, 2009, 10:07:25 PM

Me too. I despise the sleeve bearings, they almost always ruin a perfectly good fan. Plus, they have a pretty short life, due to the bearing putting a damper onto spindle speed, which also put a strain onto the BLDC motor driving chip. I'm sure the powerful fans that I put in will outlive the power supply fan.

If you think your new fan's too loud, use a fan funnel, it will help. I use mine, sandwiched with 80mm to 70mm funnel, mounted on AMD heatsink (with original fan removed).

Added after 26 minutes:

Here's a picture of a retail heatpiped heatsink that came with Phenom CPU. But I don't own Phenom yet, mounted it on Athlon 64 X2 anyways. Someone wanted me to build a computer, he let me keep it anyways, because the fan spun too slow to satisify me, and he had another aftermarket fan to mess with. I replaced it with Sunon 80mm fan, atop the fan bracket which used to hold 70mm fan, via a clear blue plastic funnel.

Smokey · April 02, 2009, 05:37:09 AM

Well i'm keeping my Athlonx2 4800+ cool with one of these...

That 120mm fan is nice and powerful... And that fancontroller is nice just in case i want a bit less noise... ^_^

Dr. Mario · April 02, 2009, 01:06:50 PM

Yeah, I originally wanted a montrous heatpiped heatsink like that one, but couldn't afford one, so I modified a retail heatsink. It stayed real cold (due to air moving through the fins fast enough), so I'm satisified with it. Therefore, I'm using AMD's Dual-Core CPU, so it doesn't produce that much heat. Phenom's another story... (but Phenom ran fine with this heatsink when I took it in for a test drive, in my PC.)
