In a previous article, someone asks about RGB signals on the Amiga...
I've lost track of who (sorry).  I originally replied via mail, but
to prevent this from generating too much traffic and (mis-) information...
(at least, misinformation I didn't start :-)

(original question:)

     THE AMIGA DOES HAVE SEPARATE SYNC OUTPUT AVAILABLE.
     --------------------------------------------------

I am using a DEC VR241 color monitor (an industrial monitor which gives
a really beautiful picture).  SYNC is driven from the composite sync
output on the Amiga.  The Amiga also has separate horizontal and vertical sync
outputs, although I haven't used these.

I don't *think* SYNC is also superimposed on the GREEN line, although I've 
never actually checked this.  If it is, then my monitor certainly fails to
pick it up.  Of course, since I got it free from someone who thought it was
broken, anything is possible :-)
