Hey all -

Just came upon an old PowerMac G4. I don't have a monitor to connect to to yet, so I'm not sure what speed the processor is and such. (The model # is M8570 if that helps anyone...)

Anyways, I was wondering if it's possible and how difficult it would be to upgrade this machine with a new processor and video card. Also, I know these old Macs can only handle up to a gig of RAM. Is there any way to expand that capability (I've got a bunch of 1 gig sticks of RAM that need a home).

Any help/suggestions would be much appreciated.

Thanks.

M8570 would make it a G4 MDD Firewire 800.

They can take 2GB of RAM.

The cheapest processor upgrade is probably a faster CPU pulled from another MDD.
If the donor Mac has a different bus speed, soldering would be required to change jumper settings on the CPU. Settings are on this page.

The fastest processor on the MDD G4's is only 450 MHz, right?

Are there any companies that sell faster processors for old Mac's?

They go up to dual 1.42GHz with stock processors.

My last mac was this very model, and I upgraded just about everything I could on it... and I realized that the cost was just not worth it. The total amount I spent on upgrades could have gone toward a waaay better intel mac. However, if 1. this will be your only computer for a long time or 2. you really have enough money to pour into it, then by all means go for it...

But especially now I would advise against it just because its a PPC and they are slowly becoming a dying breed :p.

I think you can actually get like 2.0GHz aftermarket upgrade for them.

But seriously, don't put too much time/money into it.

It would make a fine file server or web machine, but beyond that it's aging pretty fast.

i think if you have to ask "should i upgrade" - and you are financially able to, of course.

then the answer is yes
