Hello Eric:
I have been looking for RGB (BNC) to VGA converter. I also found Magenta Research is
selling one at $695. I have an old IBM RS6000 computer which used a fixed frequency
monitor with BNC RGB input. I would like to connect a modern PC monitor.
Would you think your circuit works for my case? If so, could you send me the circuit?
Thank you

Some older LCD monitors will work as-is with RGB+composite sync and
RGB+sync on green inputs. The NEC sitting in front of me, for
example, will do this--and syncs down to a horizontal frequency of
24KHz. Actually, the video cable attaches to 5 BNC connectors
behind a panel.
There are sync-combiner circuits--I used them with fixed-frequency
monitors, both in the EGA as well as the VGA days. Basically nothing
more than a 74HC86 quad exclusive-OR gate and a few resistors (and a
battery for power supply that will last for years). There are
circuits for this on the web.
