I have a c128 and a 1902A monitor and while have gotten the needed cables and everything to work I am only getting shades of gray in 40 column mode. I have tried two different cables (8 pin din to RCA and 8 pin to 5 pin), both with the same results. I verified that the monitor can display color with my NES. AND I connected the C128 to another TV in the house via RCA and it is displaying color. Am i missing something with the connection to the 1902A? Thanks in advance for the assistance.
