I never did find them. Thanks for the tip, I will poke around when I get the chance. Last time I tried it, I randomly hit various pads hoping to get lucky.
thanks,

Mot has some PDFs (well, they did a few years ago before the semiconductor group started to tank) online with the pinouts of the 603e. You can use that to find the PLL pins and figure out the resistor matrix if you haven't done it already. Excuse me if I'm telling you something you already know. The one I'm thinking of is entitled: PowerPC 603e � RISC Microprocessor Family: PID6-603e Hardware Specifications
I know where the CFG_PLL pins are, but not the resisitor pads that they trace to. :(
Was it you who was going to try to upgrade the Chips & Logic video controller to a T65225? Or was that JT? The T65220 is also on the 5x0 and 280c, right? That would be a pretty serious soldering job. If you can do that, you might as well go right for the holy grail - a faster 603e!
Yup. Already did the controller swap. It works fine, and the next step is to attempt to piggy back some more VRAM onto the exisiting 512K. It wasnt difficult. Unfortunately, trying to do the CPU swap is _just_ too difficult just using a fine tip iron. I have looked for pro shops to do the job, but I havnt had any luck.
Man, there are a lot of similarities between this thing and the 5300.
Now that you mention it, I might be able to use a 5300 board to find the VRAM address pins for 513-1024K on the video controller.....
