Sadly nothing with a Uninorth, I think the oldest schematic I ever found was for a GigE TiBook and that is a 7450 based machine sadly although that being said I think I do have schematics for a later iBook G3 if thats any use? but thats 750FX machine IIRC yeah I was just catching up on the...

ok thats seriously Awesome! the whole 60x vs MPX bus mode thing is something I have been wondering since I did my very first Pismo upgrade in December 2016! at first I did wonder if it would switch over automaticly, but later on studying schematics for PowerBook G4's etc, showed there where...

in my experiance the 500Mhz G4 7410 Sonnet ZIF has 3 settings Max-multiplier-9X mode if FSB is less than 66Mhz, if 66Mhz then 7.5 and if more than 66Mhz it goes into 5x mode for 100Mhz expected FSB operation...

heres the thread for you then :) https://68kmla.org/bb/index.php?threads/building-the-fastest-power-mac-9600.31076/

ooh yeah id be very interested in seeing an interposer developed! I know there is someone on here who has made a 7450-7455 BGA483 to BGA360 interposer to retrofit 7447A's and 7448's to existing DA/QS/MDD cards but it would be awesome to see such an interposer for all the other PPC CPU's...

Oh wow thats amazing! hopefully you can get the remaining niggles sorted before not too long and get it booting :) its actually a really good thing you added those PLL dip-switches because the achilles heel of the PowerLogix 750FX and 750GX CPUs is their base multiplier is only set to about...

in theory you should be able to boot OS X directly on an ANS without any need to swap ROMs since the ANS does run OpenFirmware as OS X bypasses any need for a Toolbox ROM image and boots directly from OpenFirmware including on OWR macs the only things you would need to do is figure out what...

one thing ill punt out there to keep in mind is that if you install OS 9 on a mac without a USB card installed, then by default it wont install USB drivers, so installing a PCI USB card after install time wont work OOB on any old world Mac I found this out the hard way back in the day when I...

its very awesome to see the home made LCIII board is finally working/booting :) it really has been awesome to see all the reverse engineering going on here, some proper hard work by some very skilled people! I look forward to further progress and seeing what else gets done in the future :)

interesting! it reminds me of the e2v 7410's etc :) https://www.cpushack.com/2015/04/09/the-e2v-powerpc-and-hitce-packages/ do you have any pics of the CPUs? do they look like new CPUs or used/reballed pulls? No problem! saves me having worry about getting to the post office! but if you do end...

Yeah :) BTW for what its worth while most ZIF's I have seen use the same pin-header with a black plastic interposer, I have noticed sonnet ZIF's used something else with a white/translucent interposer, perhaps something to look into incase it tells you where to find em or how to go about making...

here we go I managed finally unearth my 750GX/GL's! I thought I had 3 of each but sadly not however @max1zzz if your still interest in a 750GX or GL ill happily send you one next time someone in this household is going past the post office! (is your address the same as it was from the G4 iMac...

from what I understand the the 750GL was just a lower power version of the 750GX (and the lower power version of the 750FX was similarly called the 750FL) they are fully interchangeable and identical otherwise, they are the same hardware just binned for different applications :) (I have seen...

ah thats good to know :)   I have a drive-less 9600 that one of these days I really need to sort out some sort of SCSI drive for at some point! (I use a PCI ATA card for most things I do with it, but that does not work if I want to mess with the more obscure OS's like OS X Server 1.x for...

interesting little setup! if theres space perhaps look to see if a Pismo heatsink will fit, they work by having a little square plastic thing that clips onto the CPU package itself, then the heatsink is screwed onto that :)   (might be worth buying an entire Pismo CPU card heatsink and all...

Just popping in to say via tip off from @Daniël Oosterhuis this is really awesome stuff!  keep up the Awesome work ,im very interested to see how it all turns out :)   I have a (fortunately working) SE, but really want to get an SE/30 or upgrade my SE with an SE/30 motherboard!

what was the heatsink clip setup exactly? from what you describe it sounds a lot like the plastic square that Lombards and Pismos used, that would snap round the ceramic package of the CBGA360 CPU itself and then have 2 screw holes for a heatsink to screw into perhaps one of these plastic...

BTW has anyone contacted sonnet? I hear they are generally quite willing to provide detailed technical info on their old PPC CPU upgrade cards wonder just how much info we could get from them, schematics, board layout info and any technical notes would be neat! LOL

yeah would be interesting to see what can be done :)   ah cool find I had seen the first PDF but not the IBM one :)   maximum size for L3 cache is generally 2MB the 7457 can "do" 4MB but only up to 2MB of it can be used as L3 cache I wonder if the L3 cache setup you mentioned can just be...

with some semi cheap 7457's showing up on ebay it would be really interesting to see if they work on one of these sonnet cards :)   perhaps time to revisit this project? @Bolle  :)   https://www.ebay.com/itm/184311937918 I also came across this most interesting normal apple G4 CPU card...
