As I mentioned in the first post, the processor is at factory settings, set to 1.3V. I didn't make any changes. When I turn it on, it doesn't boot, there's no chime, no LED, and the Vcore slowly drops to 0.5V. I don't lower it; something exceeds the regulator's power consumption, and it drops...

Thanks for your reply, but it wasn't working before I removed the heatsink. As I explained, it stopped working when I switched from one computer to another, and I can also measure the VCore dropping from 1.3V to 0.5V, as if the processor were short-circuiting. The computer won't boot, there's no...

Hello, thanks for your contribution. I'd like to point out that I didn't want to use those speakers because they're 4 ohms, which provide poor sound definition. I've played for many years with guitar amps, both transistor and tube, and also with amateur radio stations, and the speakers have...

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...

I don't have a Wallstreet, so I couldn't flash the ROM from a Mac. So the chipset wouldn't be compatible? They both use a 66MHz XPC106.

Yes, the first thing I'll do is put in the unmodified CPU card, let's see what happens, but probably nothing will happen, I highly doubt I have a desktop iMac Wallstreet :)

Well, I'll try it: €30 for the processor with two RAM modules and several parts from the Wall Street motherboard. But I'm afraid it won't be easy, otherwise it would have been done already.

I'm afraid they don't have the same ROM chip; the iMac only has one, and the Wallstreet has four. It probably doesn't work.

Thanks for the replies. Is the ROM chip the same in the Wallstreet as in the iMac? The photos I have include RAM, and I can't see it. If I just need to unsolder the one from the iMac and solder it to the Wallstreet, I could do it. If I needed to program, I'd have to find an adapter for the TL866...

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.

You can apply the COMBO update for the version you already have installed. I have done this in the past to fix problems. It is not necessary to update to a higher version.

I think it'll work for you on QuickSilver. I cloned the same OS9 and Sorbet Leopard installation from a GE to a QS, and it works. If you have a chance to test the computer first, just plug in your hard drive and hit the button.

Thanks @DarthNvader, I'll try to see what's going on. I don't know if it'll be able to detect the error. I don't know if it has any influence, but the Mac Mini extensions I had saved in a folder were 14 extensions, and the 9250 extensions were 16 extensions. I don't know if those two additional...

Hi, today I flashed a Radeon 9250LE with the driver from this site, and the same thing was happening to me as with the 9100: "ATI Graphics Accelerator" appears crossed out upon startup. However, I found these drivers on my HDD, which I had saved for a while, and they made the graphics card work...

good job! thanks!

Today I remembered I had the original EEPROM and dumped its contents. Can help us solve the problem? I can read Radeon 8500 in the first few lines, but I can't decipher much more.

Well, I haven't looked at that schematic, but I've been comparing the datasheets and looking at the notes over the last few weeks, and from what it says there, the connection should be like this on the 744x: A[0:3] pulldown to GND A[4:35] -> A[0:31] 7410 AP[0] pullup OVdd AP[1:4] -> AP[0:3]...

Yes, I have unsoldered one and it is 1.27mm, 10x30, confirmed.

Yes, I had a 9100 on a GE, but I think it was 64MB, and maybe I wasn't using OS9 back then. We've tried at least. Thanks for your effort.

Perfect! Thank you so much!!! Even the datasheet!!! :)
