I have a thought about upgrading the RAM in a G3 beyond the usual maximum of 640 MB. I am pretty good with soldering, I could remove the onboard memory chips and replace them with higher capacity ones. The main issue is that there appears to be only 4 chips on the board and so I'm not sure how I'd go about it. All of the memory modules I see have 8 chips on them. Which means even if I took a 512MB module and took all the chips off, I'd only be able to use half of it, which means it would only be 256 MB onboard. That would only get me to 768MB. I'd like to get a G3 up to 1 GB. Anyone done any research on this topic? Is there a way to get this configuration with 4 chips? I've also seen situations where you can piggy-back RAM chips, except for the enable pin which you map to the next highest address line, but I have no idea where I'd find the address line on a G3 iBook.
