Yes, yes I did. It was from this board too. But I found this one too https://68kmla.org/bb/index.php?threads/do-any-g4-zif-upgrades-run-100mhz-bus.39573/ Did they have some extra logic on the boards, or an fpga?

This thread mentions something about it: "This is probably because those cards use PLDs/FPGAs to interface the processor to the older bus, and they apparently can't operate at 100MHz." Someone more knowledgable might have to chime in with what the reasoning was.

I mean the 9200 Mac Edition was a good OS X card for the PCI macs (or any Mac with PCI). I remember it being very speedy, especially when you enabled Quartz 2D Extreme. The big amount of VRAM was good for that too.

The first is a Radeon 9200 Mac Edition 128MB. The second looks like the HPV PDS video card from the first gen Powermacs, just a fast framebuffer.

Yeah, my 475 was resistor-swapped to 33MHz. It runs fine from the initial benchmarking I did. I was honestly surprised. Hopefully that LC040 runs a little cooler too, compared to a full 040 at 40MHz. Still just a smidge below a 840av, though, ughh.

Awesome, just awesome. Ya'll put a smile on my stressed face. The 475 does have nice and speedy video.

I know the 750GX I had for a good while in my B&W G3 could clock to 1.2GHz. I thought initially it ran at 800MHz without setting the PLL in software. I know the software had an option to do 'power-saving' by clocking down to 500MHz and then up to full speed depending on processor usage.

Woah, stabbed my replacement distributor on the 'ole Mustang and got it right on stock timing.

How about some oddball frequencies too: 35Mhz, 37Mhz. Just to try, I'm not sure how far my LC040 could go anyway.

Didn't Xlr8's Mach Speed Tools support setting that PLL too? I don't know if it had that same software problems that CPU Director had. I swear I remember trying it one time under OS X but went back for some reason.

I've always understood it was an intentional block from using G4s (specifically from the Yikes! most likely). Apple just being an a**. I think Powerlogix's CPU Director (to set the PLL) had to be updated for each version (from my time using my 750gx) and they stopped at 10.4.9 I think.

Ooo, someone could put a nice GUI front end on it, ala Daystars QuadControl or something similar.

Generally, if they had dip switches it was for adjusting the bus speeds and multiplier.

I think the Z-Force from Powerlogix had dip switch setting for up to 60MHz, I don't know if they went beyond it. The manual on the waybackmachine has its dip switch image corrupted, of course.

Anybody have any experience with those USB to ADB adapters about everywhere. Any latency to them?

Have you tried a known good PCI video card yet? Make sure to seat that PCI riser card good. I know you already do, but still

Run it in an emulator maybe.

What about Apple's Pages and Numbers applications? They're separate applications but they're pretty foolproof, being native Apple apps. I can't tell if that's what you meant by iWork. They haven't been called that in some time.

I'm going to try my 475 when I get home this afternoon, unless someone else wants to try. Hopefully my rasPi ethernet bridge still works.
