Construct a Sonnet Crescendo PB1400?
- Thread starter LC_575
- Start date
The original spec for the G3 was for pin for pin compatibility with the QFP 603e and many were made in that package, but these are EXTREMELY hard to find. Most were produced in the BGA package, and hence, need a special adapter board which puts the height out of whack for the heat sinks in laptops . . .
. . . and the adapters just happen to cost a few hundred dollars apiece! 8-o

Even though its pin-to-pin compatible.
that doesnt mean its logically compatible? doesnt the ROM have to support it? what about the chipset/memory bus?

The 740 still speaks 60x bus, so that's not the problem, and the ROMs will work fine. The problem is actually finding a 740 (and the most plentiful supply is -- you guessed it -- upgrade cards).
Pin for pin compatible means you yank one off and solder the other one down and it works. Dollars to donuts that's how Apple turned the 3400c into the Kanga G3. The only sticking point for doing a 2300c->G3 would be the clock doubling resistors. A fellow PowerDuo hacker back in the day had a few QFP G3 Procs, but he never found the "resistor" array on the 2300c MoBo to hack to get the G3 to run any faster than the stock Proc. If I ever get my hands on a QFP G3 it's ProcSwapin time for one of my 2300c MoBos . . .

Speaking of PB1400 G3s . . . I just snagged a beat up/stripped/@$$-Flapless 1400c 166 G3 off an eBay Store as a Buy it Now for all of $35.94 including shipping! [

I'll believe it when I have it in my grubby little paws and disassemble it to peek at the ProcCard, but I contacted the seller to let him know that "stock" 1400s ain't got G3s in'em, but he confirmed that there was indeed a G3 in the fugly sucker!
If it's true, it'll be posted in conquests right quick! :lol: MUAHAHAHAHAHAHAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Anybody got a Kanga available to peek inside and see if the G3 is QFP or BGA? }
I'd gladly turn one of those BiG@$$beasties back into a 3400c by doing a two-way brain transplant with a 2300c! :approve:

another issue with the duo 2300c to G3 would be, where would you dissipate the added heat from the CPU? its fanless. unless you hack a fan in somewhere without melting your keyboard keys from CPU heat.
According to the features listed on the box that my $299.95 brand spankin' new (in May of '05) from Sonnet: PBG3-466-1M CrescendoPB came in: ". . . the low-power copper technology extends the battery life by up to 30% . . ." so I've always figured that the G3 probably ran cooler than the 603e on the stock cards. But they used the Second Gen BGA G3 on their accelerators, the QFP G3 may well have run hotter than the 603e, but I kinda doubt it.
*^&<$^^%>&*^*&^()**%$!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I just tore a 3400c, that was half apart already, all the way down to a freakin' BGA 603e! FEH!!!!
There goes that donor possibility! :disapprove:

I was looking at that. Just couldn't justify $55 to ship it to me with only the possibility that it has a G3 in it. Hope you are lucky and it does have one.Speaking of PB1400 G3s . . .

So... I'm skeptical as to it being correct, but some sources claim that the lowest-end 233mhz PowerBook G3, the cacheless model, came with a PPC 740 instead of a PPC 750 on the CPU card. If someone has one of those in their junk drawer and is willing to yank the heat sink off it to see if it actually *is* a 740 rather than a 750, well... that would be a source for a BGA 740. Not that that would really help you with a Duo 2300c if it uses a QFP chip. It *might* be usable on a 1400's CPU card if you could bribe someone who has access to BGA rework equipment to help you swap it out, as it seems at least some 1400 CPUs are BGA. (Pictures of the Sonnet Crescendo 1400 cards show a BGA CPU...)
To be honest I'm finding it difficult to find evidence that QFP PPC 740s existed at all.

If it DOESN'T, he's going to need jump through some hoops to make me a happy eBayer. It's in the communications log that this particular 1400c definitely HAS got a G3 on board! }

I'm pretty sure that the ProcCard in the CrescendoPB Bag was from "Beater," my maxed out 1400c/166. I'm holding in my hand ATM and it's a QFP Proc.
I'm almost certain they do, I had a running conversation on 'fritter, back in the day, with a notorious DuoHacker about the source of his QFP G3 collection. IIRC it was a boxy green assembly for something not Macintosh related and it was an iffy proposition to strike QFP Gold or just wind up with another fetid BGA POS in your hands.
IIRC this was the same guy who managed to transplant the Video Controller ASIC from a 1400c (?) onto the underside of the Duo MLB and get it to function properly. It's too bad there's no way to search the "old guard" 'fritter archive. I was helping him look for the resistor pack that controlled the bus multiplier and I trust what he told me, he knew his stuff!

I have not read through the thread yet but it came up in a search and the post title looks like it is related.
The search does work(and did years ago as I recall).. it is just that the default settings are too restrictive.
(just as they were back then)Again, I have not read through the threads but the titles seem like they would be at least somewhat related I suppose. I only searched for QFP G3.. but the search function works.

In this thread you mention his site.. perhaps that is where you start when contacting him?

Thanks, yes, it was definitely MadDog with whom I was in touch, thanks for doing that leg work, comrade!
It's off to dreamland for me ATM!
Thanks again!
