A: the chip numbers are different in a CoCo 2.
B: the MC1372 chip in the CoCo 2 is inside the RF modulator "can" which 
might be soldered.

I have been trying to mod a 64k CoCo2 to color composite out. I have tried 2 
different mods and rebuilt one of them several times but all I
get is a black screen. I have noticed that the mods usually are listed
as CoCo1 but have read that they should work on a 2. Has anyone here
successfully installed color composite on a CoCo 2? If so which circuit did 
you use?


Here is one of the pages I used. It has 3 Composite mods and I built the 
first 2 (Fig 1 and "the Other Bob").
