I would like to build a RGB-VGA converter but I

one. If you have a circuit diagram, I would like to obtain it.
I have an old RS6000 320H computer which has RGB 3 BNC with sync on green.
It also says "separate". It also says that 1280 * 1048(something like
that). The original monitor (IBM 6091-19)has H freq =63.35kHz (something
like that), V = 60 Hz.
Could you help me with the circuit?
Thanks

I reckon if you got an LM1881 sync separator and wired the Green output to the
composite input, it'd give you horizontal and vertical sync that can be put
into a VGA monitor.
A quick Google gives this website, which details it...
