That's awesome! Great fix.

Sorry I haven't read the other thread, but don't you need to modify the ATI driver in OS 9 with ResEdit to add the device id for the Radeon 9100, similar to what's commonly done for the 9250?

This describes every compact Mac I've seen in the last 25 years, but I am not old enough to have had one when they were new.

It's probably not worth spending a bunch of time on 8.6 since anything that realistically make use of this browser should have no trouble running OS 9, but I'm sure some people would enjoy it :)

CarbonLib 1.6 works back to OS 8.6 AFAIK.

I was able to dig up a datasheet for MT58LC32K36D7 and it is in fact 5V-tolerant. That lends credence to the theory that 5V I/O compatibility is required.

Thanks @trag! I was hoping you would see this eventually. Since I posted last November, you are not even 6 months late ;) I've looked at swapping faster SRAM chips onto Apple cache DIMMs and seeing whether the TAG chips can keep up at 60MHz, but do you know whether the chips must be 5V tolerant...

Nice work! I wonder whether the reason that nobody else has posted about these caps is that the vast majority of 5xx owners are afraid to disassemble their fragile, brittle machine far enough to reach this board 🫤

Nice, glad you got it working. You can edit PC Radeon BIOSes in Windows with RaBiT: https://www.techpowerup.com/download/rabit-bios-editor/. Might be able to cobble something together with the correct timings to run the clocks at full speed that way.

Yikes, that's crusty! I agree that those are likely 4.7uF.

Right to jail. Just don't breathe the dust.

Preheat the board so your hot air station doesn't have to work so hard. This will also reduce how much you warp the board from uneven heating. You can also buy nozzles for specific chip packages that direct the heat evenly toward the pins so you don't have to keep swirling the gun around. They...

Ah, good pictures in that MacRumors thread. Yeah, desolder, replace with screws. That's the way.

I think I see what you're suggesting and it might work, but how are those studs attached to the board? Is the whole thing soldered into the board, or is there a nut soldered into the board that the stud is threaded into? If the latter, you may just be able to replace it, but you would need to...

Thanks! I just checked that card and its ROM chip is an ST 25P05V6, which means I did not pull off the original ROM chip and replace it, but rather overwrote the PC ROM with the full Mac ROM. So the PC ROM is gone; sorry about that. I have not been very careful about archiving vintage PC stuff...

Yes, that's an older (NV25-based, 2x/4x AGP) Ti4200. It can be made to work in a Mac with a custom ROM. The ROM Maker app is on MacRumors and I think MacOS9Lives, too. It takes the PC ROM as input and generates a Mac ROM. Let me know if you have trouble finding it.

You've got ten 68k machines and one PowerPC. Is there anything PowerPC-specific that you like to do with the 8500 that you can't do with the rest of them? If so, it should probably stay, if not, it should probably go. I have opinions on the others but let's start with that :)

You guys seem to be having a lot of fun :) I was hoping I could join in, but I'm not sure: I've been using this card in an old PC just for booting into DOS to test and flash PC video cards. I grabbed it from a scrap bin many years ago and kept it around because it worked, and I thought it...

Lots of Radeon 9000 news today--I got a package from Japan and this was inside: I'm not sure whether this is an OEM or retail card but it has an Apple part number sticker with 630-4254, so I guess that means OEM? Would've come in an MDD then, I think. Anyway, it has the 3.3ns Hynix RAM chips...
