Graphics chipset is something I can replace easily. As for the screens, the older Titaniums (1st gen ones) use a lower res screen, and the newer models (667 MHz and later) use the higher resolution panel. They are not interchangeable as far as I'm aware, but I may be mistaken.Compared to 1.0ghz, is the speed difference something I will see in rendering light video editing ? Also, can you fix screens ? I have a Titanium (2 of them) - one is using a lower res screen and the other one which is the higher res screen has an issue with the graphics chip + other small issues with it.
Yes, because this 1ghz Titanium I am using came with a lower res screen which works great, but i prefer my 1280 screen. I don't want to mess with it, as the Titanium parts are brittle and they can break easily compared to the Aluminum PowerBooks. The graphics goes wild when I am running youtube, but when I did a graphics stress test, no abnormalities at all, strange. IF I were to send you my titanium, is possible you can fix for a fee ?Graphics chipset is something I can replace easily.

L3 cache is external, so it'd stay at 1MB. L2 cache would be increased from 256K to 512K.1.2 ghz w/ L3 Cache 1 or 2MB ?
I have a ton of 7457s already. I can do the upgrade for $150, using one of the chipsets I have already.Ok, if I can get the chip.. 7457 and send you the system w/ the chip, how much to install it ?
Ok, cool.. I will send you the Titanium that has the hi res screen. Email me in private your address, so I can send to you.I have a ton of 7457s already. I can do the upgrade for $150, using one of the chipsets I have already.
In my experience, the lower res panel from the Onyx and Mercury models are compatible with the DVI model and later, however there is a magnet at the rear of the panel which needs to be repositioned to trigger the hall sensor near the trackpad.They are not interchangeable as far as I'm aware, but I may be mistaken.
Yep, it definitely runs warmer. I'm playing with the heat spreader to optimize heat transfer to the sheet metal cover.Awesome, glad to see it runs well. My main concern was definitely the cooling, so hopefully it stays cool enough to continue running stably. Very surprised you were able to source brand new 7400s, had no idea anyone still sold them.
Hi, I know this is an old post, but I finally managed to try an Tiger install on a PDQ 266 Mhz.PDQ Accelerated!
Not to be discouraged by a few failed attempts, I systematically went through each iteration of Mac OS X updates from 10.4.11 backwards to find a working driver for the ATI Rage LT Pro.
Mac OS X 10.4.3 - 10.4.11 ATIRagePro.kext + ATIRageProGA.plugin v1.4.4.2 (1366)
Mac OS X 10.4.0 - 10.4.2 ATIRagePro.kext + ATIRageProGA.plugin v1.4.0.11 (2895)
Mac OS X 10.3.7 - 10.3.9 ATIRagePro.kext + ATIRageProGA.plugin v1.3.26.1 (2435)
Mac OS X 10.3.4 - 10.3.6 ATIRagePro.kext + ATIRageProGA.plugin v1.3.18.2 (2059)
Mac OS X 10.3.3 ATIRagePro.kext + ATIRageProGA.plugin v1.3.8.6 (1978)
Mac OS X 10.3.0 - 10.3.2 ATIRagePro.kext + ATIRageProGA.plugin v1.3.0.11 (1734)
(Each patched to include the '0x4c501002' device ID).
All of which resulted in the same behaviour as before; Purple patches in Millions of Colors and psychedelic distortion when set to Thousands.
Until finally;
Mac OS X 10.2.8 ATIRagePro.kext + ATIRageProGA.plugin v1.2.26.32 (1679)
We now have full 2D acceleration in Tiger 10.4.11 on the PDQ! Setting bit depth to "Thousands" results in the best performance. Disabling shadows makes a massive improvement in redraw (I'm using Shadowless, but ShadowKiller will do the same).

This has made the 233Mhz/512K PDQ with 384MB of RAM a very acceptable performer with Tiger. Everything has become fluid and responsive much like the Pismo (which operates at more than twice the speed at 500Mhz/1MB with 1GB RAM).
The only downside is that OpenGL surfaces fail to initiate due to an invalid pixelformat error. This means Screensavers are broken and any OpenGL based 3D apps and games which don't have a fallback.

VRAM is now reported as 8MB (not 16MB as before). Actual is still just 4MB though.

Attached is the modified ATIRagePro.kext and ATIRageProGA.plugin drivers (v1.2.26) to install into a Tiger installation.
ATIRageProDrivers10.2.8.zip
To install, download and unzip, copy into /System/Library/Extensions/, then in Terminal;
Code:sudo chown -R root:wheel /System/Library/Extensions/ATIRagePro* sudo chmod -R 755 /System/Library/Extensions/ATIRagePro* sudo touch /System/Library/Extensions sudo rm /System/Library/Extensions.mkext sudo rm /System/Library/Extensions.kextcache
You can then reboot and OS X will rebuild the caches during boot time, but I found it's easier to ask XPostFacto to "Install Extensions", which will automatically rebuild the boot caches and allow a normal reboot.
I hope this can help some other PDQ owners to squeeze the most out of this old Mac.

try an actual fresh install of Mac OS 9 on the machine now its got a G4 CPU or on a G4 Machine then transfer the install overRegarding the PDQ with the 7400... In OS9, no matter what I try, I haven't been able to get any applications to use Altivec. On a fresh install (as well as a not-so-fresh install) of 9.0.4 (Universal), ASP recognizes the processor as "PowerPC G4", as does Metronome, Gauge Pro, and every other utility that I've got.
However, in Gauge Pro, "Altivec Support" is shown as "No". I've also run the AltiVec Fractal Carbon app and it too does not detect Altivec. I've tried going into open firmware and changing the CPU property name, changing the pvr value to some other G4, adding "altivec" property, etc., but can't seem to get OS9 to enable Altivec. I do have the vBasicOps, vBigNum, vMathLib, and vectorOps extensions enabled.
Meanwhile... I have no issues while running OS X (Tiger). Running the same AltiVec Fractal Carbon app, it correctly detects Altivec and gives me ~1.5Gflop speeds.
I wonder what magic I need to get OS9 to enable Altivec? Anyone have any ideas? (I did try loading the Sonnet Crescendo/WS software. It gave me the "Crescendo /WS" extension, but doesn't seem to do anything.)
Very nice! Thanks for posting your results. I've noticed that the 7410 CPUs can use significantly less power than the 7400. This was helpful to get a dual CPU Cube that remained fanless, but it should apply to these notebook computers as well. You can also drop the voltage to reduce power/heat. It seems like apple liked to set the voltage at the top of the range as a general rule.Anyways, just wanted to post that I successfully swapped in a G4 CPU on my original 266MHz CPU card.
Wasn't that the whole point of the 7410 so that it could be shoehorned into the TiBook?I've noticed that the 7410 CPUs can use significantly less power than the 7400.
Unfortunately, I did a complete from scratch 9.0.4 install on a blank partition. That said, it was from a mounted installer disk image while booted from an existing OS9 install. I’ll try booting from the installer disk directly to see if that makes a difference!try an actual fresh install of Mac OS 9 on the machine now its got a G4 CPU or on a G4 Machine then transfer the install over
should work then
Classic Mac OS is a bit funky, in that it only installs drivers/software for only the hardware it detects at install time
unless you manually go into the installer and tell it to install everything etc
this is why USB cards dont work on existing G3 beige OS 9 installs for example
Adjusting the core voltage down a touch should help. I'll give that a go. The 7410 isn't a practical option for the PDQ, since the cache is running at 3.3V on the CPU card and the 7410 doesn't support that voltage option.Very nice! Thanks for posting your results.

A quick scoot around the web found this web forum post.Unfortunately, STILL no luck enabling Altivec under OS9. I booted from a retail 9.1 CD and installed to a freshly formatted drive, choosing to do a Universal Install. No luck...

I wanted to check whether the altivec enabler was functioning for the G4 upgrade in my Powermac. The mac (system profile etc) doesn't give accurate information on the upgrade, so it's hard to know what's actually going on. Your program was concise, easy to use and answered the question. Thank you
Yep, I've been using the AltiVec Fractal Carbon app under both 9 and X. It clearly is using Altivec in OS X, but not in Mac OS 9 unfortunately.A quick scoot around the web found this web forum post.
Seems like Fractal generating programs were the in thing back in the day to check whether Altivec was being invoked as System Profiler was giving bum info.
I think altivec should be working without something that drasticI'm curious know if anyone could dump the rom from a Sonnet or PowerLogix Wallstreet G4 upgrade card? I'd be curious to see what they may have patched during the rom transfer process from the original CPU card.
