Almost any TV that has a "composite video" input.  Or an RF modulator., or 
the video in of a VCR.
It is close to being in-spec for RS-170.  OK, it IS "RS-170", if and only 
if you interpret that to mean "RADIO SHACK 170" (which is what they once 
did with "RS-232".

When I did lectures in Evans-10 at UC, I just cabled straight in to the 
wall jack there, to display on half a dozen large overhead monitors.
