The G4s require the copy of 9.1 that they came with; or later. A 9.2 CD should boot it just fine, though.

Today I got a G4 466MHz and wanted to do a clean reinstall of OS 9.1. I took my original retail Os 9.1 CD (not an bundled to a machine one) an tried to boot. CD-Rom starts to seek…

I have finally removed the screen - ready for when i find a new one It looks so hollow Ditty93

John - That's the version I tried first. It refuses to load in OS9. I had to dig through my collection and found a copy of 1.5f6 and that works just fine. I'm a little older tha…

I would recommend using RAMometer.... Click to expand... Very helpful discussion, and lead on the Gauge Utilities, which I have used for many years but without knowing this par…

I'm not particularly familiar with multiple processors in pre-OS X, but here's my question. If you are multitasking, and have two separate, intensive programs running, wouldn't Ma…

Hmmm. I have a 9500 with a Sonnet 800MHz G4 that has strange problems from time to time. ie Apple System Profiler freezes the machine solid when I attempt to list the SCSI devices…

Hmmm... It's been a while since I've run these kinds of Sonnet accelerators in Mac OS 8 or 9. Mine are in various NetBSD machines (I have a couple of 700 MHz Sonnet accelerators, t…

I have tested the RAM using TekTool Pro v. 3, and though I had one failure, it has passed maybe a dozen times. The documentation says that there can be occasional failures and not …

Dennis, don't you belong over on the Larry Niven group? What are you doing over here? Click to expand... I'm not sure exactly what that's supposed to mean. Are you just kiddi…

John, that's a reasonable suggestion. However I don't see an option to change the speed. I have reported sizes and speeds, then an option to enable/disable the cache at startup o…

My 8600/200 604e with 256k cache, which has an Adaptec scsi pci card and 9 GB 68-pin drive, gives a repeated "bus error" message on cold startup in 8.6. Essentially, it gets to the…

The Sonnet 1 GHz G4 CPU cards come with 2 meg of L3 which is supposed to be able to run at 250 MHz. Since turning off the cache seems to fix your problem, you could also try to run…

I may investigate this further in due course, as I know that VM will speed up a ppc under many circumstances. Only not yet.... The particular 8600 in question here had previously …

The 8600 has nearly 300MB or RAM installed, so I will leave it without VM and hope for the best for now, methinks. Click to expand... Some PPC apps will run more efficiently wi…

The mod will utilize the original color classic speaker once I find an amp of suitable size. Click to expand... Interesting, so you'll be using a low-powered external amp to dr…

This is a Sonnet card. No switches. However, CPU Director did the trick. Thank you. It took me a while to hunt down an older copy since the latest release refused to run. What…

Unusually the Quadra 630s may or may not have a full '040 - seemed to vary from country to country, I believe. Either way, you've at least two or three full '040s to work with …

Yup, that was my thought---take the full '040 from one of the 630s and put it into a 605. I'm in the process of acquiring a 605... I feel bad ripping apart a working machine, but h…
