That ought to be obvious.  The answer will most certainly be no because
the SS video board will not have a composite output which is the input for
the VOC.  It would be theoretically possible to pump the picture into the
connector at the keyboard end to get an image.

The real question is why would you do that anyway.  Since the VOC displays
the screen and the SS will display the same screen the images will be
identical (so it seems pretty dumb to overlay an image with itself)  The
only real benefit would be if you could 'freeze' an image from the SS by
turning it off, and then use the VOC to overlay that image (and thereby
have a spiffy background pic).

This would not be any good for higher resolutions anyway because the VOC
probably wouldn't cope with better than 640*400, and the output from the
VOC certainly can't exceed 640*400 anyway unless you use the composite
output which is a VCR output for maximum resolution of X*525 (depending on
whether its NTSC or PAL) where X is analogue, but remember that A TV won't
show an 80-column screen readably, although a composite monitor might.
(which means that your output won't be anygood..)

food for thought..
