[quote] what if it's dual ibm g3 deluxe whatchamacalits. <hr></blockquote>
One of the fundimental failings of the G3 was that it does not support dual configs. Sorry, no-go there! <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />
Just a side note to the heat thing. My friend has an Alienware Area 51-M laptop with a 2.4Ghz P4, and the whole left side of the keyboard (like where the cd drive and whatnot would usually go) is ALL fans. I bet there are 4 or 5 of 'em. And BOY HOWDY does that thing put out some SERIOUS heat!

The emtpy Pad is too small to take a CPU as well as it is too small for a graphics chip. It has quite few pins, I'd say around 168 or something, so its more likely to be some sort of a controller that would fit.
My guess: The motherboard is already prepared to take in a single chip BlueTooth solution there. The pad is near the SouthBridge in the area where the Cardbus controller for PC Card is,and where the Airport is located to.
Since there is also pads for a crystal beside the empty BGA pads, the controller is doing some frequency stuff (having an own bus somewhere, or generate audio, video or other signal). If it wouldnt, it could derive the bus clock where it is connected (PCI? or directly to KeyLargo?).
The respective pins are not some pads coming from the other side, such as a video chip there, on the other side its empty. The Video Chip is visible from under the keyboard, top right heatsink, you can read the "M7..."
We might see duals in the TiBook when the 7470 G4 .13 process is rolled out. Duals across the pro line would make a iBook G4 possible. Alternating power to each processor during battery only operation wouold answer both heat and power consumption problems. Advances in cooling could be a part of the mix ~ this is do-able. So go for it Apple!

Seems plausible to me. Maybe Apple designed the mobo this way for the next generation PowerBook (a move to save some R&D costs). They could even leave it with the same clock speed, or just bump it slightly, but trow in a second G4 fabbed at .13 and you get a brand-new ass-kicking hell of a laptop!
I can already see Steve proudly announcing the first dual-processor laptop in history...
Of course, that beast would probably cost you a kidney and a lung and maybe a retina too if you want more ram and an Airport card, but I would still consider it...
the processing power of two 500MHz G4s should be close to that of a single 1GHz G4, but with a slightly lower power dissipation (less heat and greater battery life).

Yes but in many tasks the single GHZ G4 will be faster especially on classic. So there is no interest to do this, much complexity, new design no more performances.

I quite agree, I don't think it is going to happen (it would also be very expensive), I was just pointing out that it would be possible to have a dual powerbook dissipating less heat than a single. It might become more interesting with 0.13 micron CPUs because they should have a lower minimum voltage limit.

I'll wait for the Quad G5 PowerBook with liquid freon cooling system and turbo blowers for maximum torque and warp speed instead. i hear from a recent Mongolian report that its coming out soon? :-)

<strong>heh... you'd need cooling vents like on the leaked pic in order to cool it...</strong><hr></blockquote>
right now, it is not feasible to do two procesors

I really dont see a dual processor powerbook for a long long time
