What sort of input socket does my television or computer monitor need to have to be able to use it as a screen for my RP?
Will old televisions work with some sort of converter?
For televisions that don't have HDMI or composite input, you can purchase an RF Modulator (Usually around $20-30 at your local RadioShack). This can take the composite output from the Raspberry Pi and turn it into a frequency that can be tuned by your television's coaxial input (usually over channel 3 or 4).

You want an RCA connector. Most TVs manufactured since about 1990 have them.
The video connector usually has a yellow (not red or white) jacket.
