I saw an article a couple of years ago that explained how to hack the video
output circuit on the 1000 to get a good signal for direct recordings.  I
can't even remember which rag it was in, but something tells me it was
Amazing Computing.  Does anyone else remember reading about this hack?

The author was really knowledgeable about video.  Apparently the hack was
quite simple, and consisted of changing the values of a few resistors in the
output stage of the video amplifiers.  Something about the way the resistors
were selected in the 1000 design was out of spec with the original design
equations for the amplifier in the composite video output.  I am a little
vague because my memory has deserted me  ;^).
