Thanks for your help. :-) I must admit, after reading all the descriptions floating around about using 1084's with the IIgs I expected this to be a whole lot simpler. cheers, MikeTo connect my Atari 1040ST to a 1084 monitor, i had to put a 50 ohm resistor on both my horizontal and vertical sync.
Since the wires are short (and not even coax), the 75 or 50 ohm resistor is not important as a termination. Therefore, it's primary function must be either: 1) to load the sync line to reduce its level so that it does not overload the sync circuits of the 1084, or 2) to provide a DC return for a capacitively coupled sync signal (but in the latter case, a 4.7k resistor would work as well, so perhaps not). -michael NadaPong: Network game demo for Apple II computers!
