Mac Forum / General / Hardware / July 2004If I have to throw this G4 away, can I put the HDD In a 266 G3?
Does anyone know whether I can put a G4 installation of OS X (put in on a 350 Yosemite board which seems to come from a G3) into a 266 FLAT beige G3 which DOES work? The G4 is nothing more than a doorstop now and, - although attractive, - can't be either fixed or worth fixing. I can't imagine I can get the G4 working by putting the G3 logic board into it WIll the OS run on the various chipsets which are in the beige G3 and is it fast enough with 128 Meg to operate properly? I dont suppose anyone has an opinion on whether there is any significant difference between a 266 MHz G3 machine and a 350 G3 masquerading as a G4? (I can put the Voodoo 3 from the G4 into the G3). The speeds do sound suspiciously similar in modern terms?

What version of OS X, and what kind of things are you expecting to do with the machine? > I dont suppose anyone has an opinion on whether there is any significant > difference between a 266 MHz G3 machine and a 350 G3 masquerading as a G4? > (I can put the Voodoo 3 from the G4 into the G3).

I'm a little confused; was an actual G4 chip involved in any part of this arrangement? G  SignatureStandard output is like your butt. Everyone has one.

However, a person can redirect his "standard output" to somewhere else, if he so chooses. - Jeremy Nixon Thanks gregory Sorry for the lack of explanation which was contained in earlier postings on which I was trying to get an update: What I have is a G4 Yikes computer DOWNGRADED by Apple to 350 MHz (because they found that 400 was too much for this board) which used a yosemite board which was apparently actually a G3 put in a G4 box. Apparently Apple wanted to exhaust all their old stocks of G3 boards for a 6 week period before bringing out a full G4. There probably IS a G4 chip in it but that is probably the only part which works as the logic board has major problems. it is probably 'beyond all economic repair' (unless someone else's company is paying and doesn't know that they can buy a better whole unit on e-bay for the probable repair cost) I thought I might try as late a version as I can manage but I have found that the actual drives have 9.2.2 on them so I wonder if I can upgrade it to X while retaining the software which is on the HDDs at the moment. I dont do any gaming at all but might want to do some minor graphics work and wonder if 9.2.2 or X it might do it better than 8.6 at 266 which I have on my beige G3 (which wont even recognise my Macally USB board)?

The Yikes! G4 is a legitimate G4 machine, but the motherboard is based on the Yosemite. It is not just a Yosemite board with a G4 slapped into the CPU connector but it's not far off of that. Unless there was something weird specific to your machine, the downgrade you're talking about was an issue of constrained supplies at the high-end of the early G4 offerings.

G4s usually had AGP video slots and earlier Macs had PCI slots. You cannot mix types of cards. It may be all your computers use PCI but just something to watch for. > There may be another issue with video card compatibility. G4s usually > had AGP video slots and earlier Macs had PCI slots.

Except the G4 Yikes! - it was all PCI. <http://www.apple-history.com/frames/body.php?page=gallery&model=g4pci> Came with a G4/350 or a G4/400 SignatureBev A. Kupf "The lyfe so short, the craft so long to lerne" -- Chaucer JWolf - more flavours than Baskin Robbins - http://macconsult.com/diaperboy/ Yes, I discovered that the hard way when I couldn't get what looked like an AGP board to work in what looked like an AGP slot (but which wasnt). I am still mystified as to the existence of what calls itslef an Airport slot on the side of the logic board with wires coming out of it dispappearing to the side of the machine but I suppose they are just antenna wires and the Airport card has to be put into that AGP-like slot. I now have the reverse situation in that when I put the G4 Voodoo 3 PCI card in the PCI slot in my 266 beige G3, it won't work at all!!
