I'm not sure if this AOC is what you are looking for but maybe it would be helpful

There have been two similar digital scopes presented in EP recently, both made by the same man - Marek Kopeć. Description of the first of them has been published in EP9/2003, the second (much faster) was presented in EP8/2004. Link given by Acek leeds to modification of scope published in EP8/2004. IMHO you should make it rather than scope from EP9/2003 - it's much more interesting construction.
