Sorry I took so long to get back to this.  Here is what I have done  
to my CoCo 3 to interface it with an Amiga 1080 monitor.  First I  
clipped R61 and R62, then I took a 74HC02 (High speed CMOS quad 2  
input nor), bent up pins 1, 4, 10, 11, and 13, piggy-backed it onto  
IC15, soldered on a jumper from pin 10 of IC15 to pin 11 of the 7402,  
and another jumper from 7402 pin 13 to the left side of what was  
R61.  All it does is take the separate sync signals and combine and  
invert them for the Amiga monitor.  As a result the connections  
should be 1/2 ground, 3 Red, 4 Green, 5 Blue, 10 CSYNC.
