AT&T 319 monitor to CGA?

[David Brown]

I have an AT&T 319 color (CGA-style) monitor that I used to use with a 
6386 with the VDC-400 video card.  I am now interested in connecting it to 
a Compaq Portable 386, which has a DB-9 CGA interface port.  
Unfortunately, the cable on the monitor is a 25 pin DB-25, which matches 
the VDC-400 card fine, but not the standard 9 pin CGA port.  Has anyone 
ever built an adaptor cable for this?  Or is there some reason that this 
will not work (e.g. the monitor expects some signal from the video card 
that is not supplied from a standard CGA interface)?  This is not one of 
the AT&T monitors that gets its power from the video card (though the same 
video card can be used to drive those monitors - I assume that's why we 
have the 25 pin interface).

Thanks in advance
