What I know;

  1. It’s name was either Copycam or Camcopy. (manufacturer ?)
  2. It was available for purchase till maybe the early 90’s.
  3. Function - It adjusted the edge sharpness on composite video.
  4. Description - Black plastic box w/ 4 rubber feet
    _____________2in.H x 4in.W x 3in. D (approximates)
    _____________1 composite in, 1 composite out
    _____________1 rotary knob on front w/ off/bypass switch (intensity)

Thanks to up front.
