I'm not fussed even if it's a tiny improvment.
What's the maximum fequency it can take? maybe if it was higher then it would be more worth while...?
The A600's chips (except the rom chip) are all SMD and not socketed. This makes replacing them very hard and requires excellent soldering skills, in contrast to older models like the A500/1000/2000/3000 in which replacing chips is very easy.
If you also want to increase the frequency of the cpu: forget it. This way, you will also increase the frequency of all other parts of your A600. There's no chance in hell this will work in any reliable way.
Making your own turbo board would be easier than replacing your A600's cpu ánd increasing its operating frequency at the same time. Seriously.
The only realistic chance you have on improving your A600's speed, is adding a real turbo board with an 68020 or 68030.
