    Hi,
	I am not very experienced with the net, so please be tender to me.

    I have an Archimedes A310 (British RISC machine) which is able to
    output 640x480 VGA video. I have a GoldStar VGA monitor as well
    (which is borrowed, so I don't have any docu with it). Anyway, the
    A310 has the following video output:
	1 Red
	2 Green
	3 Blue
	4 CSYNC
	5 NC
	6-9 0v
    Now, the monitor needs separate horizontal and vertical syncs. My
    friend and I tried to make a cable to connect the A310 to the GoldStar
    and we got some picture but it is missing the vertical sync. Not a big
    wonder because we connected the CSYNC only to the horizontal sync.
    We tried to connect it to the vertical sync input as well, but it does
    not work. Interestingly, we were able to make a cable for the
    Commodore 2080 monitor just by connecting to the horizontal sync.
    I wonder if anyone has some ideas which can help me.

    Thanks,

    Andras
