question for folks that have done the VGA mod

Hi....

I have been unable to find a schematic of the CC analog board.

So I have two questions for anyone who has done the VGA mod to a CC:

1)What is the vertical scan rate frequency in the color classic before the VGA mod?

2)What is the vertical scan rate frequency in the color classic *AFTER* the VGA mod?

Thanks.
