Just scored a G4 450Mhz! (M5158)

I was bored this afternoon - which is usually when I get into trouble... and I came across a PowerMac G4 on Facebook marketplace. He wanted $40 for it, and it looked in excellent condition. It was fully operational too. No keyboard, mouse or monitor, but since they're USB and standard VGA, I don't even care. (I have plenty of those at already.) The seller was a PC repairman, and came across it in his work, cleaned it up, installed a fresh instance of OSX Tiger and put it up for sale. So I decided it was a good day for a drive and went and picked it up. I'm hoping it will serve as a nice bridge Mac between modern devices and my SE/30s and Performa 630CD. I think I'll upgrade the RAM to 2GB from the 1GB installed. That should give it some breathing room on OSX Tiger. I may even have some free RAM lying around that it can use.

Now I just have to figure out how to install OS 9 on it for how "classic" mode works...

Is OS 9 the oldest OS it will run?

Anyway, I was just excited and wanted to share. :)

If it runs OS9 depends on *which* G4 you bought, do you know the model / processor / speed?

@Juror22 That's actually not quite true. Some of the earliest G4s (namely, very early-production Yikes! and Sawtooth) actually shipped with a machine-specific version of 8.6, and presumably, all Yikes! and Sawtooths can run that 8.6 version if one has the proper restore/install disk set.

BTW, can anyone direct me to the correct download image of OS 9.x.x so I can install Classic Mode on this beastie? There's so many on Macintosh Repository that I don't know which ones will work and which won't, and that's a lot of downloading burning and testing. TIA!

I run 9.2.2 on my Sawtooth and its wonderfully stable. Tiger never worked quite right, even with the correct firmware. But YMMV. Max RAM is cheap and easy and running a SATA PCI card with G4 specific firmware is quite a performance improvement. You can also add in an AirPort card and faster AGP card. I use mine as a software repository for 7-9 machines and it does an excellent job of unzipping, mounting, unstuffing...

Sawtooth restore. It has specific 8.6 but if the firmware hasn't been upgraded for OS X, you'll need 9.1 to 9.2.2. The newest firmware should be 4.2.8f1 and listed in Apple System Profiler.

LCARS, thank you very much! I'm gonna grab that restore CD. Extra thanks for the link.

Do you have any recommendations for a SATA card and video card?

My current firmware is v4.1.8f5.

Is this the right firmware?

Just for the sake of anyone else finding this: yes, Virginia, that is the correct link to the correct firmware.

I bought a SATA card from eBay, but apparently, I didn't do my research properly. My G4 Sawtooth won't boot with the card installed. In fact, my G4 Quicksilver won't boot with it installed either.

Can anyone recommend where to get a SATA PCI card that will work?

I’ve used the Sonnet SATA cards quite a bit but they’re a bit hard to find.

There are some flashed cards on ebay but I have no experience with them
