Hi, lately I've been finding some very strange things, things I've never seen before. Some friends brought home a G4 DA, and when I opened it up, I found two PCI cards inside that I'd never seen before. The first is a Formac graphics card, which according to Google seems to be 128-bit and...

Hi. I recently got this cable, but it needs drivers to work. The box only has the instructions, but no drivers. Do you know where I can get them? Thanks.

Hello. Something very strange is happening to me, and perhaps I'm doing something wrong, but I have a PM 7600 that has a Sonnet G4 upgrade, and it came with a non-functional SCSI CD drive. I've managed to get a couple of working drives, one DVD-ROM and one CD-RW, but both give me the same...

Good evening everyone! I've been working on this for the past week. I know it's nothing groundbreaking, it's not the first time it's been done, but I'm going to document everything I've done and discovered, and in the end, I need your help to finish it. I have an iMac G3 DV 400MHz, and I had a...

Hello everyone. A friend of mine found this PCI card with a 68020 chip inside a G4 he bought. What's it for? Is it still useful today? And what software does it need?

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...

Hi, some friends and I have been testing upgrades with their G4 Cubes. I think I remember reading in some thread that some processor upgrades aren't compatible with VRM Upgrades, but I can't find it. We're testing with an ARTMIX VRM. The Cube has the MC7447 patcher applied. I have a...

Hi, I've been trying to view the cache speed on my 2x1.42GHz MDD with OS9 and Gauge Pro, but it doesn't show any information about either L2 or L3. I can't find any app that gives me this information. Is there a version of Gauge Pro for OSX? Or what app could show me the L3 cache speed, or at...

Perhaps it's already known here on the forum, but yesterday I found this protoboard on eBay that appears to be from the Dual 500MHz upgrade for G4 Gigabit. https://www.ebay.com/itm/163629740631?mkevt=1&mkcid=1&mkrid=711-53200-19255-0&campid=5338722076&customid=&toolid=10050 It's a shame it...

Hi, a friend of mine has a nearly stock G4 Cube, and he wanted to do some upgrades. He still has the original VRM. One of the upgrades is replacing the graphics card. It must be able to run OS9, so we have two options: an ATI Rage 9000 Pro 64MB and a PC flashed PC Radeon 9250L 64MB. We assume...

Hi, I'm writing because I'm not sure what happened. I've had a Gigadesigns 7447@1.6GHz for a while now, which is actually a 1.25GHz processor OC to 1.6, from the factory; I haven't overclocked it. The Vcore is set to 1.3V. It's been mounted in a GE for a while now, and today I wanted to run...

Hi, a quick question. At first glance, they seem to have the same motherboard connector. I have an iMac G3 tray with a failing CPU card, and I could get one from PB G3 Wallstreet. Has anyone tried it? I know the fault is the CPU card because I put one in from another iMac I have, and it works then.

Hello, what's the name of this G4 processor connector? Is it sold in any stores? Does the connector have a datasheet? Thanks

Hi, this week is all about graphics... Along with an FX6200 that I managed to flash, I received a Dell GeForce4 MX440 64MB AGP x4/x8. Link According to the chip and memory specs, I should use a 270/200MHz ROM. Since it's AGP x4/x8, I covered pins 3 and 11. If I didn't, the Mac wouldn't...

Hi, although I already mentioned something in this thread, I was only asking how to adapt a SCSI disk that was not from a Mac. https://68kmla.org/bb/index.php?threads/hd-scsi-for-powermac-7600.46081/ Shortly after those tests, I decided to add a SIL3112 SATA PCI card, a 160GB 3.5" SATA HDD...

Hi, I recently found this used 128MB Radeon 9100 for a good price and decided to flash it for Mac: For flashing, as I don't have a PC, I use a TLL866 programmer and I have a few 25P10 EEPROMs to replace the original 25P05, which I have used with other graphics cards (7000PCI, Radeon...

Hi, today I received a G4 Gigabit Dual 450MHz. When I press the power button, it turns on, but the power LED stays off, there's no chime, and it won't boot. I suspected the CPU and installed a Single 400MHz, and it booted up fine, with the power LED on, but no chime. I don't know if this is a...

Hi, I'm working on this iMac and, even though I put a new battery in it, every time I start it up it shows me this message on the screen, along with the folder symbol with a question mark, and after a few seconds it boots from the first partition. Even if I select another partition in the boot...

Hi, I'm starting a lot of posts these days, I hope I'm not bothering you. I was reading about the Mezzanine port on the iMac G3 tray loading, and I see it was a "normal" PCI port under a non-standard connector, the mezzanine. Is this true? If so, would someone with circuit design skills be...

Hello, I am writing to you because the information on the Internet is getting lost. Many years ago I overclocked the FSB on one of these iMacs from 66MHz to 83MHz, but I don't have the documentation and I can't find anything on the Internet. Does anyone remember how to do it? Any photos and...
