Are the Upgraders going to die soon?
Surely there can't be that many people left with pre G4 macs that are going to upgrade using products from Sonnett, XLR8 etc. In fact there probably isn't any point upgrading a G3 mac faster than 350MHZ.
Why are there no upgrades?
Is Moto denying these chips at Apples request? Seems most likely
Is Moto having yield problems? Not very likely, there are lots of other fast G4 customers apart from Apple.
Is there a technical reason? I've heard so, but I think its all BS. Remember when Apple deliberatley released a firmware upgrade that killed G4 upgrades, Sonnet/xlr8 found a way past it in a few months. Possibly.
How long do you speculate the upgrade co.s can servive with their 500 G4 upgrades, and stupidly overpriced dual G4 upgrades? I'd say about a year before they pull out of the market, if they can't get faster g4's

At least they can be overclocked.

And no, AI rumors are no better, and SpyMac is no better and on and on - SO WHAT? So just because Meader's rumors have been worthless for a longer amount of time makes them more viable?!
He sucks, his site sucks (same tired design even!) and his information swallows - hard. At least The Register and Think Secret are *sorta* close at least *half* of the time...MOSR blows goats though.

Just let him do whatever he wants, after all you dont HAVE to read his stuff.

I don't know what the technical barriers are to using a newer chip like the 7450 on an older mobo, but he didn't sound encouraging as far as future procesor upgrade speeds. At least not from a G4 owners' perspective. For someone with a G3, a 667MHz G4 upgrade would be pretty dern good.
<strong>I don't know how true the comment about Motorola rigging prices so companies like Sonnet can't afford to buy chips in small lots, but I recently got an email from one of the tech guys at Sonnet and they basically said for those early G4 users who are looking for a SP upgrade, it may not come for a while yet and when it does it may only be 667 MHz or perhaps 733.

Well, for my lowly 350, I'd consider such an upgrade if it were priced right (<$300). I'm not optimistic though.
[quote]<strong>

</strong><hr></blockquote>
Nope ... the uni-north ASIC in my G4 is too old; it won't accept a dual processor. You see my dilemma.
I was wondering if it was due to pin differences. The ZIF socket used in the G3s and early G4s meant a fairly easy upgrade for any ZIF mac owner (my 300Mhz B&W was very happy when it got a 500Mhz G4 in it). All these processors during this time had the same pin layout, so they'd fit straight in.
The highest upgrade chip speed I saw was a 500mhz G4. When this came out it was damn expensive, but it was within a few months of Apple lauching the (then) top of the range 500Mhz PowerMac. Throughout 1999/2000 we didn't actually see any faster chips. Apple played for time with the '2 brains are better than one' dualie range, and I think several upgrade companies followed suite with dual G4 upgrade boards. My memory is more hazy but I have a feeling they may only have been compatible with Sawtooth-model G4s. And I'm not sure if they ever actually shipped ... I'll go read up on this inna bit
The first G4 speedbump we saw in over a year was 466, 533, 667 & 733 at MWSF2001. Was this the introduction of the G4+, and did it use a new pin-structure/number which wasn't easily backwardly compatble with ZIF? I was reading the Moto press info on the Apollo Monday, and remember thinking the reference to the pins, which it commented was backwardly compatible with the previous generation of G4s, which started with Digital Audio PowerMacs, and have been musing this.
I'm only speculating, but I think it might it might be to do with this, and also not working on the 66 or 100 Mhz buses of previous G3/G4 models. The'Digital Audio' PowerMacs were the first to use a faster 133Mhz bus speed. Could it be that the mobos on older machines, already some bottleneck on older machines with newer upgrades, became too much of an difficulty to justify developing upgrades for these machines?
I'm not sure if economics or engineering issues have have killed off upgrades for older Macs, but I don't think we'll being seeing any more on ther market in future. Which is a pity, because like many people here, I have an old Mac, which i upgraded, and it's served me well. When I buy a new PowerMac in the next 6-18 months, I'd like to think I'll be able to upgrade it as well as I had my smurf-tower.
PS Got a PowerMac? Old or even a new Apollo? Pissed with the ATA bus speeds and on a budget? Spend £100/$100 on an ATA/133 accelerator, buy some new fast hard drives and REALLY feel the difference. And don't buy Sonnet .... the products are great, but they just buy Acard PCI cards and rebrand 'em. I've bought from both, and I was pleasantly surprised when I discovered Acard and saved myself some money and was able to make a beige G3 so much faster. My B&W screams too. Sorry for the deviation :cool:

I don't believe the technical limitations....if upgrade manufacturers can put a G4 in a G3, then they can put a G4 in a G4, know what I'm saying? There just haven't been any dramatic changes in the G4 processors that would be obstacles to upgrading. I don't expect to be able to put a dual G5 in my Sawtooth, but hell, is it too much to ask for an 800 MHz G4 upgrade?
Apple is insane of they think that more people will buy towers if they can't buy upgrades for them. I know many PC users that like Macs but would never buy one because you cannot upgrade them, and I totally understand his point.
Apple should have at least one line of computers that is fully expandable and upgradeable. If they slash this feature from their lineup then the value of Powermacs plummets.
Sometimes I think Steve Jobs is on a crusade to fill landfills with as many Macs as possible.
866MHz no L3 - $299
866MHz 1MB L3 - $399
866MHz 2MB L3 - $499
866MHz 2MB L3, Dual - $899
Replace 866 with 1GHz if you want.
<strong>This is so depressing. I originally bought my Sawtooth G4 with the intent to upgrade the 400 MHz CPU in a few years, but now it looks like my Tower is no more upgradable than the disposable iMac. WTF!!
</strong><hr></blockquote>
Well, pretty much the same is true on the PC side (only motherboard and CPU are much cheaper). SOme reasons you can't stick new processors in many older boards are: Lack of support of low enough core voltages, different pinouts, different sockets / slots.

I'm not so sure. The original G4 (7400/7410) definitely could be run on the old-style 60x bus as used on the G3 and earlier PPCs (and in fact that's how it was done on the Yikes board). I'm not quite sure the same can as easily be done with the 744x/745x series. Also, the latter feature a completely different package, so this might be a problem too.

That's just not true. Try sticking an Athlon XP in any first generation Athlon board - no go. Neither with socket478 P4s and early P4 boards. Or even with Tualatin P3s and early P2 or P3 boards, even.
And besides, for most people, upgradeability would encompass a bit more than just CPU and mainboard, I guess.

I don't think so.
If you could just replace the CPUs on a Mac easily and for little money, how many people do you think would actually have opted to buy a new Mac in the last couple of years as opposed to just shell out a fraction of the cash for a new CPU, some RAM and maybe a new graphics card?

This is not quite true. The 745X series all can run on either the MPX or 60x bus. Therefore there should not be too much of an issue to run a 7450 in say a B&W machine. In fact, if you look at the Mot sps site and check out their evaluation boards, one of them has a MPC107 memory/PCI controller and clearly states the 7400/7410/7450/7440 is supported on the 107. The MPC106 is the memory controller used in the B&W and the MPC107 is just a 133MHz version of the 106. They both exclusively use the 60x bus and not MPX(I think the beige use the MPC105 but I could be mistaken). Check out <a href="http://e-www.motorola.com/webapp/sps/site/prod_summary.jsp?code=SANDPOINTX3&nodeId=03M943030 450467M98653" target="_blank">this site</a>.
And the package shouldn't be a problem. It's a BGA (uses solder balls instead of pins) anyway so it needs to be installed on an interposer board to connect to the external cache and socket.
I think the main problem is that the upgrade manufacturers have become lazy and basically copied Apple daughtercard designs. Now its harder and they have to design them from scratch. That may be the reason they are taking so long.

Note that I said "I'm not quite sure it can be done" rather than "it can't be done".

Maybe the old boards can't provide the proper voltages? At least this is the case with the last generation of P3 processors and earlier motherboards...

Yeah, actually I find that kinda interesting - if I remember correctly, even several years after the MPX bus first appeared, Apple's core logic chips (UniNorth / Pangea) are still the only controllers capable of actually using MPX bus - everyone else, including Motorola themselves (!), support 60x mode exclusively, wasting quite some potential of the G4.

Hmmm, I seem to remember having seen pictures of one of the daughtercards somewhere on the net, and it sure looked like the G4 was soldered directly onto it with no additional layer in between. I'll try to find the link...

I thought about that too, but then kinda wondered why they wouldn't be able to just carry on copying Apple's designs? Why would it become harder all of a sudden?

Well for one thing, If they wanted to make a 750CXe or 750FX upgrade for the B&W or beige they would have to use some unique designs since Apple never used those in those machines. And i'm not sure if the 750 and the 750CX/FX are pin compatible. And ditto for the 7450 in those machines. But I'm not sure why they haven't gotten to the sawtooth machines at least... those have been out for a while.
<hr></blockquote>
There are many reasons to buy a new Powermac besides the CPU. Bus, memory, agp speed, all those can be good reasons to buy a new powermac. Everytime Apple boosts bus and memory speed, that's an incentive to buy a new Tower, and for many people who need the fastest hardware available, they will opt for a new tower over a new CPU. A Sawtooth Powermac running even dual 1 GHz 7455 G4s is going to be considerably slower than a new Quicksilver would be.
You also must consider the the extra powermac sales to people who consider upgradeablity an important feature. Like I said, I know a few people who won't buy a Powermac because of the lack of CPU upgrades.
I also think you'd be surprised at how few people replace their Towers for a simple boost in speed. Most Mac users I know would be inclined to upgrade the CPU, but not the Tower itself. They consider it too much work to transfer all their old apps and files to a new computer, when their old one works fine. Even many B&W tower owners, or even beige G3 owners, see no reason to buy new hardware since their Macs are plenty fast for all of their needs. I'm talking about Life sciences researchers who use their Macs for word processing, data analysis, graphing and presentation design, desktop publishing, and internet. These people will update to OS 9, but not to OS X because it requires new applications and too much adjustment time.
My point is, Apple is probably overestimating the number of sales they lose to CPU upgrades. The fact that Moto's pricing discounts only apply to 10000 CPUs or more, and that this is a hurdle for the upgrade manufactureres, tells us that they aren't selling very many upgrades.
Anyone have any sales figures for the CPU upgrades? I bet they are quite low, even back when the first 500 MHz G4 upgrades became available to G3 owners.

That's actually about the point I'm most ready to accept in favour of CPU upgrades.
But otherwise, compared to the PC world, deterioration of value is several orders of magnitude less on the Mac side: Whereas selling a 3 year old PC just isn't worth the hassle 'cos it wouldn't be worth much any more, people are willing to pay insane (by PC standards) prices for used Macs.
Thus, I think that just selling your old machine for a good price will in most cases be a much more economical option than upgrading it.
