This might be of interest to video frame store/capture enthusiasts.

This particular version was designed to capture up to 8 fields of video (works for pal or NTSC as noted in the article) and the memory output DA converted back to video to make it independent of the computer and software. However with the memory IC type used it would be very easy to clock the 8 bit memory contents of a captured image out to a computer. The story behind it is here:

I think I have some formerly commercially available deals that do the same thing. 1U rackmount jobs, as I recall, except they're probably NTSC only,rather than both.

If there's any interest, I could probably excavate them.
