Hello All! I am running Panther OS X 10.3.3 on an elderly Gigabit AGP G4 400 with 512 MB of RAM. While this machine was comfortably fast running OS 9, it became sluggish and unresponsive with OS X 10.2. Especially the Finder feels annoyingly slow. Panther made this a little better, but it still is too slow to be fun and is almost unusable. Going back to OS 9 is not an option for I love Panther for the UNIX and had so much trouble with OS 9 which is all gone now. Therefore I started experimenting with overclocking and was very happily surprised when I successfully overclocked the CPU to 500 cycles just by removing one resistor from the board. The effect was astonishing, the responsivenes was back and the machine was usable again - stable at no noticeable temperature rise (fluke probe measures 26-28 C, same as before). It was fun working with it again but for a small but very annoying detail: In black text over light background a few characters have a lime-green halo. Some kind of strange shadow that seems random and does not go away or move. It does this in OS X only. OS 9 is 100% OK. I was hoping that this might be a minor problem which can be fixed by another tweak in HW or SW. It would be a great gift if a solution could be found that would enable me to keep on working with this babe for another year or two - now that I am starting enjoying her. Any thoughts and suggestions would be greatly appreciated. Thanks and regards, gsl.
