Sorry dude. The T2K and most things from that era
output ttl (digital) color information. Modern
multisyncs require analog input. Ain't happening.
That is the least of your worries. Any reasonable monitor will have a 75
ohm input impedance and will expect a 1V-ish analogue video signal. TTL
outputs are 5V-ish. So you need to drop 4V, so you need a resistor of
4*75 = 300 ohms.
So if you connect a 300-ohm-ish resistor in series with each of the RGB
signals, you can feed a TTL signal into an anlogue monitor. You only get
8 colours (if you have an I line too, like on a CGA connector, it's a bit
more work to make use of it). But you will get a useable picture. It's a
kludge, sure, but...
Besides, modern multisyncs will probably only sync
down to original "low-res" VGA hsync frequencies
(31.5khz). The 2K outputs 24-26khz, I don't remember
That is the bigh problem. Converting a monitor to work at different
(horizontal) rates ia a lot of work.
