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
