I have seen it before. I know I have but I don't remember what it was
called. I went through my books and can't find it. Somebody help...it
is hurting my head.

Cool! I'll try it.

Seems like a lot of work...unless of course it worked better than 3080s. I
just thought it might be a better vca....only kidding about not needing
600/700s.

I tried a few more things with it....whatever "it" is it's fun to play
with.
