Multiple floppies in one system?

Joe,

I think I remember using a Videologic DVA-4000. It was used to overlay NTSC
video over VGA video. If I remember, you setup a specific color "block"
through the VGA, and the NTSC came through that "window." Kinda like my
understanding of Chroma-keying (sp?) Another thing it could do was overlay
the VGA with "transparent" NTSC.

We used it for demos of a ruggedized PC we were building at the time. It
could do some impressive (at the time!) stuff. I don't recall the
programming particulars, but don't remember it being that difficult.

Let me know if you want further info.

Gary
