The 'silent upgrade' Mini G4's have an external TMDS that fixes an issue with the Radeon 9200 chip used in the older Minis with a pixel clock limit below that of full DVI. In theory the silent upgrade is better, we just need to figure out some issues with the 'NDRV'.

Didn't the Beige come with a SCSI CDROM and a SCSI 100 ZIP drive? That's how mine came. Like I say Rev. A Beiges don't 'support' drives on the slave bus of ATA, it's not going to work correct that way. I'm unsure if Rev. B Beiges support slave devices, pretty sure Rev. C Beiges do. What is...

Are Are you sure you have the correct ATI ROMXtender extension installed in Mac OS 9? The reduced ROM was reduced by removing the 'NDRV' or Native Device Driver, both OS 9 and OS X will need a disk base 'NDRV' for the card to function in the Mac OS, this is what the ATI ROMXtender is, it's a...

Rev A Beiges don't support Slave drives, that could cause oddball issues.

This 32MB Rage 128 is also listed in the 'NDRV' too, I think they did exist on the PC side, so flashing one should not be that hard, but any Radeon is going to out preform it, so nobody ever bothered. It was not until the Radeon 7000 PCI that we figured most of the flashing stuff out. I...

It's just the Sonnet 700MHz-1GHz upgrades are so rare and expensive that not many people are going to hack about one. Were all the 700MHz Beige only, or were there later versions that were 'universal' and still 700MHz?

So they added the FPGA so it could be used in the Beige and the B&W/Yikes, it was not a technical limit of the machines themselves, but rather Sonnet didn't want to design two upgrades. Piss poor reasoning in my view, slowing the bus and memory down by 1/3 was a bone head move on systems...

Did you forget the link?

Does anyone have any specifics on what issue caused Sonnet to limit these to 66MHz bus operation? Has anyone ever tried 70Mhz-100Mhz to see if the bus can be clocked higher?

It would be nice if someone took this project to Old World PPC Mac's. We have some software to modify the 4MB ROM Images, but no hardware to new ROM SIMMs to program. I'd really like to do some custom ROM's for my Beige G3 starting with the v3 ROM for OF 2.4 support. Moving on from that we...

It's interesting, I wonder if the Rev. 3 BootROM may have had a USB Open Firmware package? It would be kind of cool if it did, we would not need ADB KB after this mod. Someday I'm hoping some one will make the ROM SIMM for the Beige Mac's so we can do some ROM modding on these machines to add...

What about a photo optic CRT calibrator? It's an odd beast being ADB, but I don't have any CRT's to test it with.

Never mind, I found it.

There was a Mac OS 9 application called "Throughput" that tested the throughput to the PCI bus. I don't remember, I think it copied from RAM to VRAM and benchmarked the copy speed. Can anyone find a copy of it, please? The file name maybe "Throughput.sit" if you want to search your old drives...

Not sure what you mean by PCI GPU for headless hardware acceleration in OS 9. If you mean you want to use the PCI card as a 3D accelerator without ever connecting a display to it, that really can't be done under OS 9. It works somewhat under OS X with ATI cards like the Radeon 9100 PCI, but...

No the Mach 5 CPU from a Kanas board will not work in a Nitro architecture logic board. The Mach 5 CPU has 1MB inline L2 cache running @ 100mHz on the CPU daughter card. As you have said the Nitro architecture 8600/200 had the L2 cache on the logic board.

That was my thought too.
