 Sorry dude. The T2K and most things from that era
output ttl (digital) color information. Modern
multisyncs require analog input. Ain't happening.
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
exactly. There are a number of hurdles to overcome to
get something like that working with a modern monitor.
 As a side note, I've requested info on the scan
doubler made by Princeton. It allowed you to use a CGA
card with one of their monitors that took ~400 lines
of res like a 2K. I guess it was a good idea for
people who had a CGA card, intended to upgrade it at
some point, but avoid obsolescence w/the monitor. The
reason I decided on buying a multisync right off. 
 I guess I could contact Princeton...
 And the other thing that would be nice is a way to
convert a ttl signal to analog. Doesn't sound too hard
to me...
