I am just finishing up on a project that mixes two video signals, one of 
which is an analogue or digital input (the 2nd is fixed), and output is to 
analogue or digital monitor. It handles any resolution and frame rate (in 
and out), and the hardware supports composite, S-video, RGB (eg. VGA) & DVI 
video on the input. Also does up-scan and down-scan conversion in hardware.

I'm yet to 'play' with it, but I plan to hook up all manner of micro 
computers, including the Coco and Amiga. I'll post pictures when I do get 
around to it.

But yes, a very, very expensive scan rate converter! :)
