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
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!
The 2300c has 512k of VRAM, right? I can't seem to find it...
Man, there are a lot of similarities between this thing and the 5300. It really makes you see how little NEW product development was going on at Apple in the 90s. Most of this stuff was evolutionary and moving the components around on the logic board to make it smaller...
Peace, Drew
