Great!!

I've finally finished the recap and it's still the same, nothing has improved. I can't imagine what the problem could be. Even the Sonnet Tango isn't working.

Hi, after reading your reply, I decided to try it. First, I recapped the PSU. Although the capacitors weren't showing any problems with the checker, I replaced them. Nothing changed. Then I replaced some capacitors near the PCI slot (I didn't have more time today) and it's still the same. I...

Hello. I've done some more testing. First, I added a battery because without it, every time I unplug it, the PRAM is erased and the patch is lost. I tried three PCI cards that I have, which work perfectly in my G3/G4 processors. None of them worked in the 6500, and the Sonnet Tango froze on...

I've tried both OS 8.6 and OS 9.1 without the Ethernet card, and I get the same result: there's no power to the card. The photo shows the PCI device information (the Ethernet card was still there; it has an 8139 chip, but it seems to be recognized as 8129, which might explain why it's not working).

Thanks for this information. I'll follow your thread to see if we can find a solution. I can't use OSX; the highest version I can use is 9.1. I was considering the possibility of a hardware problem with the PCI riser, but if it works under OSX in your case, then it can't be that. I also tried...

Thanks, I already installed these drivers, as I mentioned in my first post, and it's not working.I've downloaded from Macintosh Garden many times, but I haven't been able to access it for a few days now, and I don't know why. I haven't done anything wrong :).I'm in Spain.

Hello. I just tried it and nothing has changed. The USB card still isn't working; I don't even have power on it, and neither the mouse nor the keyboard lights up. Apple System Profiler shows the same information as before. I ran the patcher. The first time, it said there were 0 KB in that part...

Yes, I understood that. I meant having a working battery to run the patcher. I gather that if I run the script and restart, without powering off and on again, I can do it even if the battery is dead.

Thank you so much! I'll try it this afternoon. My battery isn't working anymore. If I don't unplug it, if I run the script and restart, will it work? Otherwise, I'll have to provide 4.5V somehow temporarily where the battery connects.

Hello. A few days ago I received a Power Mac 6500/250 that works fine. I've installed Mac OS 7.6.1, 8.6, and 9.1 on different partitions. I wanted to add USB and Ethernet support, so I added an NEC USB 2.0 card that I usually use in my G3 and G4, and a Realtek RTL8139B Ethernet card that I had...

Okay, you win, yours is better, but try putting it in an iMac tray :P I tried putting in two 128MB DIMMs (actually two 250MB ones, with only half of each recognized), and it worked. It seems the limit is 256MB. And the OS9 system profiler doesn't show the speed correctly.

Hi, good suggestion. I just tested it by moving the same module from the bottom slot to the top slot, and it works too. Now I'm wondering if when I tried 128+128, both were 100MHz. I can look for two 100MHz ones this afternoon; I don't have time right now. Thanks for your suggestions! P.s. my...

Well, I'm making progress... I tried swapping it for two 128MB RAM sticks, but it still wouldn't turn on. So I removed the top stick and left only 128MB underneath. It turned on!!! But take a good look at the photo: It has the Lombard EEPROM installed, 2.5:1 ratio, the processor is running...

Hello. It's been running fine at 460MHz and 2V Vcore until today, even booting at 500MHz on occasion, I don't think it's due to voltage. I recently added these RAM modules; they're two 512MB PC133 modules, each of which only recognizes 256MB, so I have 512MB. It hasn't given any problems...

Hi, I just tried that, but it didn't work for me. I've tried both 500MHz and 450MHz, and I hear the chime, a crackling noise in the speakers, but the orange LED stays on. I tried this last, simplified combination you mentioned.

Well, it kept the Lombard EEPROM, with the processor at 466MHz and the L2 cache at 183MHz. It didn't work at 500MHz. It now has 200MHz cache chips. I'll try testing the 100MHz this week, although I'm afraid I'll be limited to a 450MHz processor.

Thanks so much for this contribution! I'm going to try it on my iMac! Great work!

Yes, perhaps when turning on this processor model, it produces a voltage drop sufficient to knock out the device. I have photos of a Gigadesigns for Cube with an MC7457 that has lower-capacity capacitors (4 x 150uF) on the 5V input. Perhaps if I remove the capacitors from the input, it could...
