  1. 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 example) so its good to know there are a couple more options still beside the SCSI2SD (I would love a SCSI2SD but they bit hard to justify for me currently with how pricey they are, the V5.x's are not bad, but Ideally id want a V6 to make full use of the 10MB's SCSI bus in the 9600 and the
  2. 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, as while I dont think finding the heatsink on its own would be too hard, finding the little clip on its own might be a bit tricky) said plastic clip thingy is also shared with the Lombard but they have a much smaller heatsink that being said, you could JUST use t
  3. 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!
  4. 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 squares could be used or adapted to replace the broken original setup? out of curiosity what SBC is it exactly?
  5. 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
  6. 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 used in 2MB mode with the last 2MB ignored? (like 512MB SDRAM sticks in a G3 Beige or BW G3) I do still wonder how L2 cache is set/detected by Uninorth based macintoshes, I know there is an SPD chip on the CPU card that contains the info but I dont know wh
  7. 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 fitted with a 7448 on an interposer board to go from CBGA483 to CBGA360 https://forums.macrumors.com/threads/g4-7448-and-7457-swap.2233532/page-2?post=28563255#post-28563255 it would hilarious if you could use such a interposer-board here as well a 7448 9600 w
  8. what you need is the sonnet L2/L3 cache enabler for OS X http://www.sonnettech.com/support/kb/kb.php?cat=319&expand=_a2_b169_b230_b154_b228_b74_a13_b233&action=a3
  9. its a Radeon 9200 Mac edition the sticker on the back will say Mac on it and the card looks like this hopefully this helps keep in mind while 7.6 will boot with the 9200, you wont have full graphics acceleration
  10. user @dosdude1 offers such a service specifically for old macs I recommend you get in contact with him and check out his youtube videos
  11. here is one max1zzz helped me out with when I was also getting started with all this BGA upgrade fun https://forums.macrumors.com/threads/diy-g4-cpu-upgrade-round-2-putting-the-power-into-flowerpower.2040272/
  12. the annoying thing about Apple Open Firmware on the G3 BW and newer is if it does not recognise the CPU thats been installed it will halt on purpose, older Firmwares like found in the beige Macs, will actually boot on an unknown CPU, obviously all the "extra" bits like L2 L3 cache dont get enabled but at least they boot thats what the Giga Designs Firmware patch me and Dosdude1 used for the iMac G4 thing does, unlike the more developed firmware patches from sonnet and the like, which will mask a CPUs PVR etc all the Giga Designs does is remove the "halt on u
  13. for OS X, Xpostfacto includes an OpenCHIPS6555.kext driver (or something along the lines of that name) might be worth having a poke at?
  14. im in the same boat https://forums.macrumors.com/threads/powersurging-to-mac-os-x-10-5-8-power-macintosh-9600-fun.2144305/ sadly I have not been able to find much these days like the OP, if anyone knows where to get some for relatively cheap lemme know
  15. shame about the L3 cache vanishing, I have never had much luck with TSOP chips myself. with no L3 it would be a good board to experiment with, try a 7457 on it? those have 512KB of L2 so should help with the loss of L3. BTW have you tried contacting sonnet for some details on the CPU card? A friend of mine doing stuff like we do contacted sonnet for info on the TAM G3 upgrade cards and actually got back a good wealth of detail
