It has a thin cable coming out the back which is RF combined
audio/video (mono, I think) with an RCA end on it, not F-Type threaded coax. I'm not making this up.
That still means you need a tuner. Demodulate the RF, and separate composite video from audio.
On the other hand, there is a "monitor" port on the side of the
computer which is female DIN5 with (I've read) chroma, luma, composite, audio (mono) and ground pins. One could probably build an adapter cable for either composite out or S-Video out. One reference I found suggested that chroma isn't actually available on this model.
That sounds easiest. If you already have composite, audio, and ground pins on a single connector, just wire new connectors. Considering the age, my guess is the DIN5 connector is the same an old keyboard connector, the large round DIN plug. Just cut off the plug, and wire in RCA jacks.
