It is my understanding that the IBM vga cards can NOT be setup to
work with a TTL monitor.  Further I assume that this monitor is a old
style TTL.  If it is (or can be analog then this is even simplier).
All the clone vga cards I have used do have a setup mode or switch for
use with TTL monitors.  Generally with this option is a setup for lower
res monitors than the max of the card.  Simply, set the card up for
ttl output, and make a cable for the monitor.  It should work just fine,
else you can try it to see if the monitor has a analog mode.  With a ttl 
monitor on a analog ouput, you probably will get a picture but the color
mapping will be history and terribly unstable, basically unusable.
