Hacking an RS-170 tap into a B&W TV set?

  Given nothing but the set; no doc of any kind (have you Googled for a
Sams Photofact of it?) I would get the number of the CRT, find the
control grid pin, and trace that wire from the socket back to the board.
That will get you in the neighborhood of the video amps - then some simple
signal injection [even a metal needle using 'hum' injection from your body
capacitace] might show up some traces where demodulated video lives. You
can then experiment with the proper place , right coupling capacitor,
polarity, etc., to apply the computer video.

  If you have a scope, this can also be done by inspection, rather than
injection.

  The usual Cautionary Parables about working on naked TVs apply. zzzzap!


  Cheers

John
