OK .  Thanks.  I have replaced this board with a Color Classic II board.  I thought I would use my original color classic logic board to try to do a re cap my self.  That way, if I screw it up, I will still be running my color classic II board.

But I do not know what that part is, and if I can buy a new on on, say, Mouser or Allied electronics.

Can you tell me what it is and what I should search for?  It is the crystal right?

Thanks
