An item on eBay surfaced... which claims to be a Macintosh G4 Quicksilver 2002 Server Logic Board (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2020903080&r=0&t=0&showTutorial=0&ed=1020723326&indexURL=0&rd=1)

* 800 MHz or 933 MHz PowerPC G4 processor; or dual 1 GHz PowerPC G4 processors
* Four (4) 64-bit PCI Slots
* Four (4) DDR RAM slots (yes, DDR!)
* Velocity Engine vector processing unit
* Full 128-bit internal memory data paths
* Powerful floating-point unit supporting single-cycle, double-precision calculations
* Data stream prefetching operations supporting four simultaneous 32-bit data streams
* 256K on-chip L2 cache running at processor speed
* 2 MB DDR SDRAM L3 cache per processor, with up to 4 GB per second throughput (933 MHz and dual 1 GHz systems)
* 133 MHz system bus supporting over 1 GBps data throughput

Not sure what it is... as I doubt it is as advertised...

my 2 cents...

it doesn't look my Quicksilver Dual 800 motherboard.

It's clearly got 4 dimm slots... current Macs have 3.

Whoa Nelly!

Now this is an interesting piece. Does anyone know if the board, by just looking at the picture, is the same board shape as in a current QuickSilver?

It makes for interesting conversation regardless.

And why is it red? I've never seen Apple use a red cicuit board before.

Pic of the current Quicksilver motherboard: http://homepage.mac.com/macspeedzone/.Public/images/hardw/reviews/comp/a/quicksilver/733/heatsink.jpg - looks the same as my Dual 800.

Note the image in the ebay item looks "reversed" - in that the slots are on the wrong side... note, this could be a simple "flipping" on the image that was done at some point in the picture->upload process

couldn't find any info on the seller( location, etc).

he's only sold OS 9, X and FCP in the past.

it says its from a test system-if so, apple may still technically own this( if its real) and this item may disappear off E-bay when apple finds out.

may be a hoax or glimpse into the future:)

On the bottom of the page, the listing says that all hardware is refurbished unless otherwise noted. So, if this is to be believed, this board has been out and used, and then returned and refurbished.

If that's true, don't you think we would have heard about it before now?

It says that it is using DDR, however, he says the Bus speed is 133 mhz. I don't smoke crack, so isn't that impossible? Last time I checked you needed to be at a higher system bus to run DDR?

A 133 bus speed would mean be effective 266 DDR.

Well those are definatly DDR slots. Look at the seats on them. I just pulled some DDR out of a system here at work, and they match!!!! If this is real, it is a radical deisgn change though. Look at the pic that arn posted, and the one that I threw up that was corrected. Major differences in the board design itself.

Looks like the rumors (like the one I posted...pats self on back) are very possibly true.

Lets all hold hands, sing Kumbaya, and dream happy dreams....

Well if the red is an indication of a prototype, how can this guy get away with selling it? I'd think it would be exactly leagal, but I don't know much about this sort of thing.

So this board would support a total of 2 gigs of RAM, which would be nice, and its faster. Its going pretty cheap so far as well. But why would the power source be 28V? That ones got me curious.

Backtothemac
May 2, 2002, 03:21 PM
Duke,
That would be 4 GB of ram on the board, not 2. Also, the voltage could be because of multiple processors, or due to the memory bandwidth?

If apple do get it pulled surely this would be an admission on their part.

May 2, 2002, 03:48 PM
Could, possibly, a G4 support DDR if some kind of memory controller made it look like standard RAM to the G4?

ie: the memory controller talks 133 Mhz DDR to the memory and 266Mhz standard SDRAM style to the G4.

Just a thought.

But if the PPC 7450 and 7455 doesn't support DDR-ram, could it be a logic board for a new chip? Like the G5..? :D No, serious. It doesn't look like a fake, so i would assume it's made for another chip than todays G4's. Maybe a 7500 if there exist such a thing..?

eric_n_dfw
May 2, 2002, 03:53 PM
As a second note, where does Motorola say that the G4 cannot support DDR anyway? Given the right chipset, why shouldn't it be able to?

Looking at the little blurb on that PPC roadmap (http://e-www.motorola.com/webapp/sps/site/overview.jsp?nodeId=03M943030450467M983989030230) I don't see DDR mentioned for the G5 either. (They do mention RapidIO though, which I am under the impression is a whole new technology anyway)

Are those 3 fat, short, black things ATA ports? Do you think it has RAID support built in, without getting another PCI card? And what is that white port next to the 2 black ones? (not the port next to the ram, but the one next to the drive connectors.)

I looked up the QuickSilver logic board, since Apple is using the SAME one for both desktop's and servers. The reason there is a price difference is the server software, not the motherboard. They do use a slightly different power supply on the server (redundant unit). Still, it looks like a fake-up to me. Notice that the ATA slots are in the wrong location on the one on ebay.

IF this is a prototype mobo, then he is seriously violating his NDA, as well as any agreements with Apple to get prototype/beta units. I really think that someone should report that to Apple. I know that someone here has to know who to email at Apple, since I don't.

I'm attaching an image of what the QS mobo looks like, so that people can see the locations of all the stuff.

It would be stupid to sell a fake thing on eBay. You get totally screwed if you dont send what you had in your description. I bid on an iPod(never received, and eBay reembursed me for it, I dont know what they did to the seller though), so I just bought from Apple. But my point is that maybe one of us should bid on it to see if it is real.

IF ANY OF YOU DO, AND IT IS A FAKE, I AM NOT RESPONSIBLE FOR ANY LOST MONEY OR WHAT-NOT.:)

Okay... this sure looks like a prototype board and sure looks like DDR memory slots...

...but....

[edit: nevermind... it seems like this guy was just cuttin and pasting some text from current g4 specs]

It sure looks like it has some kinda AGP slot but the person doesn't list it. Is it the same as we have now?

I'm also in agreement with the person who questioned the CPU location since it wouldn't allow for the heatsync.

Finally I have a brandy-new DP G4 Server in my office and the ports are not the same. The modem is on a riser and the 2 usb ports are 'one on top of the other' and not 'side by side'.

now I am assuming that the port between the ethernet and the (2) firewire ports is a modem jack but the more I look at it I'm not so sure...

No matter... it sure looks interesting. Maybe dorsal from the AI boards will comment on it.

well I now know what it is (the DDR MB mentioned in the main www.xlr8yourmac.com news page today) - but I can't mention the specifics...

Prototype apple motherboards are red - so that should be one clue.

I suspect once it's seen by the mothership that the auction will be closed.

Let's just say the next G4s are going to be interesting ;-)

If he did steal it, he is not being very smart about it. Maybe the guy wants to get caught and go to jail, I wouldn't.

As for things to come.... maybe the G5 will be released similar to that, but I have to believe that Apple wouldn't change the locations of the IDE and ATA slots on the motherboard. At least, not to where they are being shown. For as long as I can remember, since the G3 blue, there has been at least one ATA port/slot at the base of the motherboard, right after the PCI slots. That facilitates mounting drives on the base plate of the computer. Putting them where they are shown in that photo wouldn't make sense. It would also restrict air flow around the motherboard.

I still vote that this is a fake.

USB 1.1 and 2.0 ports/cables are the same I believe. I wouldn't imagine that they would change ports to go from Firewire 1 to 2, so that it can be backwards compatible.

May 2, 2002, 04:32 PM
This would make sense for rackmounts. The different configuration of ports, the use of DDR memory, and more memory slots. I wouldn't expect this "update" for the towers. Apple wouldn't update a mobo without updating processors. Why would it still use the current processors? Even for testing? That pic on ebay is the heart of Apple's new rackmount.

I guess we won't know if Apple is releasing a rack mount option until they announce it. Maybe this is an example of such, but I don't recall reading that it fits into a xU rack.

We will see what happens when Apple makes their next announcement, either at WWDC or MWNY.

It definetly looks like it's in for a case re-design. The thing that bothers me, though, is that if the motherboard looks like it woudl fit into the case with all the ports on the bottom, and the PCI slots on the top so that the power supply / drive cables don't have to travel through the whole case. The only reasons that I can see for this design are:
1. A true, desktop form factor case. (but those are kinda stupid and impractical, and would hamper Apple's easy-upgrade efforts)

2. Rack mount form factor.

I don't know much about the different form factors for rack mount computers, and I have no real idea why anyone would want Air Port in a rack mount, but this is the only other way that I can see this motherboard fit practically into a computer. I do know, that this would justify the use of built in RAID (even though it would be nice on the regular desktops)

I do think that the processor card connects just to the right of the RAM slots, on that white thing. The port between the ethernet and firewire looks like a modem, but it may be a little small. RJ11 is a little smaller than RJ45, but not a whole lot... I guess it must be a modem...

The only other thing that I can think of, is that this guy is really good with red paint, motherboard parts, exacto knives, and super-glue... In which case, he has some explaining to do to e-bay. Either way, though, he has explaining to do to someone, either e-bay, Apple, or us...

Rower_CPU
May 2, 2002, 04:36 PM
Rack mounting could account for the odd mobo shape and layout...

This is pretty damn intriguing! The best rumor-fodder we've had for quite some time, too.

If it's fake, then I hope Apple has something equally cool on the way.
If it's real, then I hope we see it soon!

Firewire 2 uses a different connector... with an adapter avail to use older devices I believe...

Improved connector

New connector needed for higher data rates

- So let's make everything better
Much better shielding and signal isolation

- Designed for both CE and PC worlds
Only slightly larger than existing 4-ckt connector
Carries power to support PC peripherals


there's a picture of the new connectors.... very well could be.

I haven't a clue about Apple's engieering practices. That said, I have some points to make and questions to ask.

As this is presumably a prototype board, mere physical differences in how components are mounted or positioned do not exclude it from being a prototype board or suggest that a new form factor is afoot.

Does anyone know what Apple's Advanced Computing Group and/or the engineers that actually build prototype boards how they do or do not employ bread boards? Why go to the trouble of soldering components for prototyping when one could simply use a bread board? I guess a board as depicted would be as it is so that Apple can ship it abroad and/or test it for environmental factors.

This board could be a year or more old for all we know. When would Apple, a major computer maker that is renowned for employing cutting edge components, first have access to DDR components?

Also, I should think that Motorola cranks out many different flavors of CPU's for prototyping and sprint development efforts. So, if the posts regarding G4's lack of support for DDR is true, then it seems to me that it would not be unrealistic for Apple to receive experimental or prototype variations of the G4 that do support DDR.

Other than the DDR, are any of the other features different or unusual, such as the pre-fetching feature. Also, what is the deal with the floating point unit? Like the vector processor feature mentioned, is this simply part of the G4 itself?

What I would find really interesting about this so called prototype board would be if something really unusual were to be found on it. Does anybody really think that Apple doesn't have prototypes with DDR? Come on! If they didn't, Apple would be one seriously ****ed up company.

Something really interesting and unsual to be found on a prototype board would be some special ASIC (proprietary) that serves as an OS X accelerator for various functions. Something like this might suggest an x86 move, for example, because it would help prevent hackers from simply porting MacOS X to any white box or Dell rather than by Apple hardware.

So, in short, I find this so called prototype board very disappointing. A 133 MHz motherboard!!! If that were what we are to see in the next motherboard, Apple's future would seem awfully grim to me.

I can see it, especially FireWire 2, for RAID arrays. Faster then SCSI, and more flixible too. USB is good for input devices, you could even attach wireless keyboards and mice to the server and work on it from a distance (6' +/-). I would rather see those options on it, then have them removed. Many people use FireWire on a daily basis. It would also facilitate faster file transfer if you needed to put several GB of data onto the server. Plug in the FireWire drive and dump it all fast. Otherwise, you will be waiting for the infrastructor/network to funnel it all in.

May 2, 2002, 04:58 PM
The size, shape and indent on top of that mystery connector sure looks similar to the Firewire 2 connector in the PDF file Arn attached.

The eBay post says that it was used for less than 12 hours. Doesn't that seem odd, especially for a server where you want to test it under load for days and days if not weeks?

If this board is legit, maybe it suggests that one of Apple's other proto boards was markedly superior and this one was abandoned.

Actually, rack mounts would be great for clustering macs for CGI and compositing work, in which case, you would still want USB and Firewire ports. It might be intended to work with Cinema Tools and (speculates Nothing Real product in future). Clustered macs would let you edit and composite film at it's native resolution.

I agree, except about the 133MHz bus. That's a 133MHz Double Data Rate bus. Or 266MHz effective speed. Same as an AthlonXP. Anyway, something like this board is exactly what I've been predicting since sometime around MWSF.

Eirik

Sounds like it to me.... if you had a prototype Apple board with DDR before such a board was even released, would you sell it if it was any good?

It would surely be full of bugs.

It seems wierd to me that Arn posted up information about this eBay product and the Firewire 2 possibility within it. These threads may go together.

I would carefully assume that Apple has some sort of Firewire 2 product under development, or that the product is finished.

Any other assumptions?

I believe that the photo on eBay is correct.
The image posted in this thread was reversed un-necessarily.
for those that want to see the photo, here is the link to the item in question.

Proof that the eBay photo is not reversed:
Look at the battery.
I am holding an identical battery to the one in the photo.
The color pattern is not reversible into a mirror image to match.

Well, I am not so sure that, if he wanted to fake it, eBay would be the place to do it. Realisticly, if he got away with the sale, he would still have to send something when the sale was finished or he would be really screwed. eBay is for the real thing, SpyMac is for fakes.

Tell me about it.... not only 4 DDR and Firewire 2 but also 64 bit PCI.

Not too happy about the 133MHz bus, though..... that is just wrong. If Apple released a 133MHz board with DDR all my happines will be gone. What good is having fast RAM if it is then bottlenecked to 133?

I wonder what the planned AGP is? I would LOVE to take full advantage of the Ti card instead of having a cut back version.

133MHz system bus = DDR266

So actually they wouldn't be too far off, but since we're hearing about DDR400 and DDR533 coming down the pipe soon, hopefully Apple will be on the forefront this time and not trailing WAAAAAAYYYY behind the memory bandwidth again. :rolleyes:

Hi,

I want to clear up a thing here: there's nothing weird about the 28 volts power supply: it's necessary for powering an AGP video card with ADC connector on it. (28 volts, 4A). The lucky ones who have downloaded the picture can verify this: in front of the AGP slot there's a small brown connector, similar to the one on my own G4/500 motherboard. It's being used by my Rage 128 for supplying the ADC with power.

This link (http://www.applefritter.com/prototypes/pdm/index.html) to Applefritter says that Apple uses different color motherboards in the prototype process— blue, yellow, red, and green.

They show another red motherboard for a prototype 6100.

Maybe I have to calm down all my spontantious ideas running around and around my head but we in the Apple world need to kick some serious butt. I want Apple to drop the "beautiful" image in the PRO line and push a truely beautiful and beautifully blazingly fast image. 133MHz is getting on and is being readied for all consumer machines.

Why then was there a big flag on the ebay page saying make sure your system is compatible with the 28v. I guess it doesn't matter now that the board has been taken off ebay. I wonder if someone is feeling undue pressure right now from Apple?

I wish the guy had run a few benchmarks on the prototype before he sold it. I imagine memory bandwidth hungry stuff like photoshop and audio plug-ins would have run quite a bit faster than current models can, even if the CPUs were exactly the same.

I was reading something on the Pentium 4 the other day and at 2 Ghz, it's got a 20 x multiplier, the bus speed is rated at 100 x 4.

This would probably mean with a custom memory controller a G4 could easily run DDR RAM at 133 x 2. As far as I know the maximum multiplier on a PPC7455 is 10, if so we could have a 1.33Ghz G4 with 2Gb of DDR Ram later in the year if this prototype isn't scrapped in favour of something even better.

If the guy is for real, he is a moron. He says he hopes to do it again if he gets the oppurtunity. Anyone with half a brain wouldn't say or do these things. So his words are not to be believed, but the image is IMO.

What I am saying is that if you have a product like that and you sell it, the chances are that it is not as good as it is sounds due to bugs because it is only a prototype. Remember, prototypes are made because it is almost 100% impossible to make a new technology with no problems the first time. The guy who gave him that board probably found problems with it and since then Apple has probably had a new Prototype.

The thing is, PLENTY of people would buy this board for what it is not thinking about the fact that if it was totally working it would not be a prototype

Even if this thing is an actual prototype board by made Apple, it doesn't tell us much about what's actually coming our way in the near future. I am sure, and as others have pointed out, Apple's been testing DDR Ram, firewire 2, and other goodies for while now--these aren't new technologies. The fact that these things are being tested doesn't mean much to me as a consumer.

The only potential new information this gives us is that Apple could be playing with a rack-mount server design. But again, this is pure speculation. And again, this is a prototype, at best, so it may never see the light of day.

The mere fact that this now-famed board has on it what we have all been specualting about in a concrete, semi-legit picture is just mind-blowing. We're all consumers here, but with allegations like these, we throw consumerism out the window and crank the drool factor to 10.

Screw all speculation, this is what we've all been waiting for. Even if it is just a prototype, it gives us more reassurance to further our suspicions/hopes. I guess this little episode epitomizes what this site is all about.

I still think that it's a conspiracy created by Apple to get us excited, and to see what we say about it in forums like these. In that case:D :

Just 133mhz bus? Where is RapidIO?
Only support for 2 processors?
That thing better support up to 2Gb of RAM
Nice RAID support. I hope it takes advantages of many advanced RAID features...
The case in store for this beast better have 2 front end accessible drive bays, and up to 4 HD's inside...
Give it all the cooling you want so you can stuff as much into it as possible! Pro users are usually more concerned about what their machine can do, not how quiet they are. If they want peace quiet, they can get an iMac...
Firewire 2, nice...
If it is for a rack, how about hot-swappable hard drives? eh?

If anyone else has anything to add, please, contribute. Apple may have their associates here at macrumors...

Remember, you won't get it until you ask for it. Apple may be a great company with certain powers, but they can't read our minds (90% of the time, that is, but there is much unknown about Steve's RDF...)

based upon the following:

A) i tracked down this guy's location by looking thru his other auctions. he's located in Moorpark, CA. which is right outside of simi valley and not too far from thousand oaks.

B) his other auctions are OS9, X and FCP system cds-small easily nicked items

C) he states the DDR really speeds things up-so he's seen it run but c'mon, if he had it on his own system he'd NEVER sell it.

D) he's dumb enough to try and sell it.

i think he's an intern or a "tea-runner" for a post, FX or animation house--one of the biggies that gets beta units.

and since apple knows where EVERY one of their test boards go and is most likely accounting for them right now....

Let me say a few things that I've noticed.

The board is deffinately an Apple prototype because of its color and the circuit lines are visable. So that discounts the spray paint and super-glue theory.

The mysterious "1394b" connection is not that for one reason. Firewire 2 is ment to be able to accept normal firewire 1 connectors as well. In other words it is backwards compatable just only at the slower speed. The connector in the photo is more shallow then the normal firewire connections that are obvious. This would mean a firewire plug would not fit in it properly.

Rapid IO will not be around until the G5 and Apple is of course working on DDR compatability for the post Apallo G4 chips. What is a possibility is G4 chips with DDR for the consumer lines and G5 with Rapid IO for the pro line.

Since the birth of OS X Apple has realized that the market is there for rack mount designs and has had prototypes for well over a year and a half. So this board might be that old. But one thing is for sure that is a connection for a G4 daughter card on the mother board. Another small trend... red mother boards tend to be near their final design phases there have been pictures of red MB 6100 prototypes (just one example) that look exactly the same or very close to the final green MB. Some times I think Steve is like what they said about god in the movie dogma, I wonder what kind of laugh we give that guy sometimes... either that or grief lol.

Take a look at the PDF arn posted on Firewire2/1394b. It has a NEW plug architecture to manage the higher bandwidth. The ports shown in the PDF look exactly like the ones on the mobo.

If you look back at the picture, you can see that there are two standard Firewire ports on the mobo to accomodate 1394a.

Alright I stand corrected on two things the 1934 is supposed to be 1394 damn numbers I need to just stick to firewire lol. And two yes the ports are not backwards compatable... I did a little photoshop overlay of the img of the MB and the outline of the new plug and they look a lot alike. I still think it is really shallow though not even USB 1.1 or 2 is that shallow a plug.

Well, afaik there are no desktop computing processors with core voltages higher than 5 volts. Nowadays, most processors run with core voltages under 3.3V, often they run around 1.8-2.2V.
I've learnt this when I was trying to overclock a standard Apple 120 mhz 604 card to over 150 mhz with a faster crystal. On the card there was a special power supply to downstep from 5V to the core voltage.
So my bet is that the 28V will only be used for the ADC, and who knows, maybe it will be used for the FW2 port?

There is a LOT more power needed on the board than just the processor. There are, as you know, 2 USB ports, 2 Firewire ports, the USB, Video and power that goes into the ADC as well as a few other things.

MOST IMPORTANT, though, is that a 23" Apple LCD has a maximum voltage of **duh da duh da** 28V
Anyone suprised?

It's my understanding that RapidI/O is a crosslink between two processor cores or the same chip. Of course, I could be dead wrong. But I DO know that the G5 is supposed to have two cores on the same chip, with a super fast crosslink.

I read it somewhere...i think IBM's site.

Well, this may sound a little technical, but as you know the other parts on the mobo are all standard components, which means they can be put into a PC too. Therefore, they have to work on 5 or 12 volts. The only thing that might need a higher voltage might be an audio-amplifier (black heatsink on the red motherboard?).
And b.t.w., power is measured in Amps, not in Volts, and if you take a look at your power supply it will most probably have something like "... 5 volts 25 amperes ...".

Being not only a newbie, but also an arts guy, I have little technical understanding of hardware. I have been trying to compare the by now infamous motherboard photo with the sketch of a QuickSilver motherboard, to identify the various connectors, but to little avail.

Perhaps some of you "in the know" could make a copy of the mb photo, with text identifying the various parts? - and post it, naturally

None of the comments here have touched upon the connectors that seem to be on the underside of the board (it being semi-opague, vague shapes can be discerned through it). Notice that the shadow of the board shows it to be slanting, indicating that there are connectors on its underside.

Isn't the brown connector in the corner for a modem?

From a purely consumer, non-techie standpoint, I have to say one thing...

Has anyone else noticed that everything that might be seen from the outside (internal parts of the plugs) is snow white?

A snow white rack mount?
