ok i coped out… Mark give me a

So i used it to over clock my Quadra 800 to 40 mhz.
I acutely replaced the cpu with a 40mhz 040 as well.
It runs at like 41.48 says the speed-o app that came on the floppy with the Mac-Clip.
It seems to me like the macclip is a little hokey. Its not on there all that well.
The Macclip thing clips right to the OSCILLATOR chip on the mainboard.
Disabling it and inserting its own clock.
Maybe i'll put a drop or 2 of goop to hold it on there a little better...
