Updating to 10.4, seeing if that was the issue.

Hello! I'm doing a firmware patch on my iBook G4 (it's an 800MHz board with a 7445), using the Giga Devices patch, I do everything as it should then when it reboots after the tone it gives me "Boot-ROM Flash is off", anyone have any ideas as to how to fix this? I tried the uninstall option and...

We figured it out. R49 and R48 are in parallel and then R47 is in series with it. This makes up R2 on the formula for the vCore... vCore = 1.23 * (1 + 10k/R2) These here Just copied from my TinkerDifferent post :p Shout out to @Bolle for the help over in the TinkerDifferent Discord, and...

@3lectr1cPPC @Byrd I got the Mainstreet card in and it had a 750 instead of a 740! So I soldered a 750S on, and am overclocking it. The IBM PPC documents for what I installed say 2.0V or so, the Motorola ones (what was on there) is 2.6V.

Hello! I'm looking for any documents which will give me the needed information to adjust the vCore on my PowerBook G3, I replaced the CPU and it chimes, but the vCore is far too high for the CPU and I need to turn it down. Any help would be appreciated! It's a Wallstreet BTW, but my guess is...

Take a break then

Hmm, can I see them probed again

Look over the same points with an oscilloscope to see if they have improved

Let's see first if the 74LS fixes it, as broken RAM circuitry can cause cascading problems.

Trace that as well

I'm a student so I'm always around. Have a great night!

Well here's to hoping!

I'd still replace it, it looks kinda funky still.

Looking on eBay, the AM79C950s are like $6.50 USD, if worst comes to worst.

Strange, reprobe with the keyboard connected then

If there's a button then you press it If not you need an external degausser, which I have no experience with. Someone else said it might be the yoke

I want to say you've got to degauss that monitor. There might be a button on it, but it looks bad so you might have to actually externally degauss it.

Hey, whatever works! As long as it's a 74LS32 it'll work. Let me know if that fixes it, I think that might be it.

The chip appears to be a AM79C950 Wikipedia says this is used through the ANS and PM9500 as well, and it is a combined SCSI, serial, and network controller

Based on the board layout I'd say this chip
