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...

Hello everyone. I recently found a very cheap iMac G4 700MHz because it wasn't working. When I checked, I saw that it was the PSU. The optocouplers were failing. I changed them and the power supply has come back to life. Now it turns on and makes a "chime" sound but the screen always does the...

Hi, I recently purchased an iBook G4 1.33GHz, 133MHz bus, if I'm not mistaken, it's an "early-2004". I wanted to try overclocking but my motherboard doesn't have the PLLs where this link indicates: overclock iBook G4 Does anyone have the location and configuration of the PLLs for my version...

Hello, how can i found the pinout of the connector of the build-in display of the 190? I want to try if it is possible to adapt some modern display like this: display 9.7" I have an 190 with degraded display:

Hi, I recently purchased a Shappire Radeon 7000 PCI PC version. My intention was to use it on a G3 B&W. Since I don't have a PC, I first installed it in a secondary slot on the G3 and from the system profile it indicated that there was an ATI graphics card, but the screen was black. I purchased...

Hello!! Today I managed to raise the Mac Mini G4 10.2 from 1.5GHz to 2GHz WITHOUT CPU SWAP. This Mac Mini model comes with a more modern Freescale CPU. It is capable of reaching much higher speeds, but as I already explained when I performed the CPU SWAP on a Mini 1.25GHz, the impediment is the...

Hello, I've been playing with an iMac G4 800MHz GeForce2 for a few days, and I've been writing for a few hours now, so I'm not going to go into much detail. In my blog I have reported my SWAP on an iMac G4 800 that works stable at 1.3GHz...

Hello, it is possible to use some "modern" SCSI-3 HD with 80 pin port, with 50pin-80pin adapter in this Power Mac? The adapter is this: https://es.aliexpress.com/item/1005004639042334.html?spm=a2g0o.order_list.order_list_main.5.1a28194dxKExW3&gatewayAdapt=glo2esp And the HD may be one of...
