Hi, I like this mexican system. The interesting question is:
How does a colour picture looks like compared with the three colour system

.
Our VGA monitors are RGB and so it is possible to connect G and B. This is the same result as connecting the kathodes of a picture tube.
I made a little two colour VGA adapter. So I am able to see the three colour picture without adapter and two colour with adapter.
I made some screenshots for you. The mexican system is better than expected. If you don't know the original you will accept it

.
Kind regards,
Darius
