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)

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).

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.
