Well, finding a composite video point is trivial,
therefore.
Inside the modulator can, I fear.
I had another look inside last night. The two metal cans appear to be
video circuitry (on motherboard) and modulator (separate). They are
linked by a 4-way ribbon cable of which one conductor is ground. I
suspect the remaining three of being video, line sync and frame sync.
(They could, I suppose, be composite mono, U and V but I doubt it)
Someday I must
get a decent TV standard monitor - probably the Barco I
sold to my brother for use as a telly - but I ought to have a composite
Err... You do not use a Barco monitor as a TV. It's far too nice for that. I
happen to have one, you see.
Au contraire, the Barco is one of the few pieces of kit I _would_
consider using as a telly (the other being my Bush TV24 of course).
Not of course. There were Barco's with built-in
PAL, SECAM or NTSC decoders
OK, you win.

Pretty boring, I'm afraid - 8245 and 6110 plus about 20 TTL chips. I
can't read the numbers of the chips inside the video can unless I
desolder said can from PCB.
