I guess that the connections are:
    R = Red
    G = Green (possible with syncs on this line too!)
    B = Blue
    H = Horizontal (or composite) syncs
    V = Vertical syncs
Thus the R,G, and B outputs from the Archimedes should go to the
R,G, and B inputs of the monitor. If the archimedes outputs composite H and V
syncs then this should go to the monitor's H/C input otherwise seperate H and V
syncs should go to the appropriate individual input on the monitor (I can't
remember what the Archimedes puts out in the way of syncs!).
