you want to boost your old apple g4, ok let's try to integrate this accelerator, it changes your g4 400mhz to 1,2 ghz, now you can use your g4 with a lot of plugs, audio tracks and more, i bought it in september 20, at the apple expo, you have 3 years of warranty, and i never use it because i bought a new powermac, follow it and enjoy with it.....
