Yes thanks, I am prepared, and I also read what to do if I totally mess it up (which had something to do about creating my own external 1 mhz clock externally to kick it into life sortta thing.) but I should read the instructions carefully (only there aren't any easy to understand ones I can find :p)
I did test that it was using the crystal as I removed it while it was running and everything stopped, then plugged it back in and it started again so that must mean I'm using the crystal right?
