Greetings all...

Recently just acquired my first Mac. From the looks of it, it seems to
be a G3; Its in the "blue&white" casing, hockey-puck mouse and matching
keyboard. Looks exactly like it does from photos of a G3 except for the
fact that my box does not have the giant "G3" on the side of the
machine. Just the Apple logo.

In System Profile my hardware specs read as the following;

Machine Model: Power Mac G3 (PCI graphics)
CPU type: PowerPC G4 (2.2)
Number of CPU's: 1
CPU Speed: 450 MHz
L2 Cache (per CPU): 1 MB
Memory: 256 MB
Bus Speed: 100 MHz
Boot ROM Version: 152

Again, I have no way of telling if this was an original G3 but upgraded
to a G4, but by the looks of the insides, it dosent seem to house an
upgrade card or anything like that. Looks stock.

So by these specs can you determine if I have a G3 processor or a G4? I
would like to upgrade but unsure if it already has been upgraded to a G4.

Blessings,

JT

sounds like the CPU was replaced - a IF cpu replacement.
no additonal card -
so from the system profile I would say it has been upgraded to a g4/450

Is it possible to upgrade it even more? I just ordered a stick of 256 MB
for more memory, but what about the processor? Could I just get a better
G4 processor, or would I need to get an upgrade kit like the Sonnet Encore?

Those B&W G3 logic boards do not "like" more than 768mb (3 pieces of 256mb
PC 100 RAM).

You'll need a ZIF (zero insertion force) upgrade. You take out the
processor that's in there, and insert a new one. Sonnet makes them, you
can also get them from macsales.com. The more expensive ones tend to be
easier to install. Just make sure you read the installation notes
carefully. If you foul things up too much, you may need to re-install
the original CPU to get going again, which it sounds like would not be
possible for you.

IMHO, I'd leave it alone. Stuff it with RAM, but leave the processor be.
The really fast CPU upgrades will cost you a couple hundred dollars less
than a new eMac, but won't get you the performance.

Thanks for the tips. I checked out some websites on mac upgrades. They
are pretty expensive given that it would only increase proformance say
20-30%.

I pulled another stick of RAM out of my old Pentium III box sitting in
my closet. I now am running my G3/G4 Mac w/ 512 MB RAM. No proformance
gains at all, BUT things are moving a bit more "smoothly".

I will consider this then end lifecycle for this Mac. Until HD DVD/TV
becomes more mainstream, Ill continue to use this Mac...

If you haven't already, you should check out this review at some CPU
upgrades. That 450 should do you fine for now, so it'd be mainly
informational. If you get OS X, a faster proc wouldn't be too bad:

http://www.xlr8yourmac.com/G3CARDS/G...iew/index.html

When the G4 processors first became available, Apple was not ready with
a totally redesigned mother board for the G4 chip.

Instead they took the existing G3 board (in the blue and white case) and
reworked it a bit to accomodate the G4 processor. I believe you have
one of these.

Later they came out with a redesigned motherboard specifically for the
G4 and I believe the speeds then started at 500 MHz and up.

If the case is Blue&White, you have a "Yosemite" machine that has been
upgraded to a G4.

It should. The upgrade would be non-obvious, visually, since the CPU
card for the G4 looks pretty much the same as the G3. And a heatsink
hides much of it.

You provided your own answer above in the System Profile listing:

Looks like a B&W G3 with a CPU upgrade.

Probably not. Almost certainly not.

The first G4 ("Yikes") systems used modified Yosemite motherboards, and
they show up in System Profiler as "Power Mac G4 (PCI graphics)". And
they used the gray version of the system case.

The G4 (PCI graphics) and G4 (AGP graphics) systems were released at the
same time, September of 1999.

> and I believe the speeds then started at 500 MHz and up.

They shipped systems at 350MHz and 400MHz. The first 500MHz systems
didn't ship until July of 2000 (thanks to Motorola) when the G4 (Gigabit
Ethernet) PowerMac was introduced.
