Latest version of DSO 068

Hi all

I have just started building my 068 and noticed that I have the version i of the board.

Would it be possible to get the updated schematic for this version?

My main reason I am asking is that R32 seems to be missing from then kit list but there is still space on the board for it.

Thanks

Stu

Please see attachment. The major changes were:

1 ) Use U5 for crystal oscillator instead of U4. U4 clock is driven by U5 pin 12. This makes the clock more reliable.
2 ) Deleted buzzer circuit which is not related to oscilloscope operation.
