[comp.sys.amiga] amiga composite video

rogoff@itsgw.RPI.EDU (David H. Rogoff) (08/21/87)

  I know this has already been discussed, but because of a screwup/
  emergency, I need to ask again:  what is the mod to the 1000 to
  make the composite video level normal.  Please post or email very
  soon to make a video arts professor I know very happy.

    Much Thanks

The (excellent) article, "Quality Video from a Quality Computer," in
Amazing Computing, volume 2., no. 7, explains just how to do it.
Essentially, what you must do is change a couple of resistors.  The
result is a composite signal that is at least "industrial-quality."
Unfortunately, the details are too long and complicated to go into
here.  Also, you really need to see the photographs in the article to
see where all the parts are located.

I suggest you call PiM Publications (Fall River, Massachusetts) and
see if you can order that (back) issue of Amazing Computing.
