I have a couple of 70s/80s "home" computers
(e.g. Radio Shack Color
Computer) that are intended to connect to a TV set. They don't have
easily available composite video, even internally, only modulated RF
output. Currently I have an old CRT TV that I use with them, but for
various reasons that isn't practical long-term.
Does anyone know of a small TV tuner that tunes old analog TV channels
(US NTSC) and outputs composite or VGA or HDMI signals? I've looked
around a bit but haven't found anything. It's relatively easy to build
one, but I would prefer a pre-built solution. And I'm sure others have
run into this same problem.
VCR,
Digital converter box,
Closed caption decoder
even some TVs have a composite out, all of which had RF input
All of those are now old.
Not all of those have composite output out, but such do exist for each of
those.
You should know that your specific example, Radio Shack Color Computer,
can produce composite internally with trivial modifications.
A large number of such machines internally share a common RF module; if
you identify the input to their RF modulator, often clipping onto that may
be all you need.
