It does indeed, and on a separate board, too!

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
one as well (Barco is RGB, of course). At present the monitor I have
requires Video + Composite Sync - or it can free-run and generate sync
for a TV camera.

I can't remember offhand, except that there are quite a lot of them.
I'll have another look tonight.

There seem to be two large rectangular metal cans - one with its own PCB
(probably the UHF modulator) and one on the motherbaord (VHF for US?)

Philip.
