first. hello to all guru people

i searched thru the whole google & co, i can't find any information on the 1803 monitor (not the 1083

) ??
i saw one on a pawn shop but they dont want to activate it.
there's just 3 buttons on it, plus the on/off, and a peritel SCART . and i can't find any clue if it's black&white or color monitor ! (due to so few buttons i'm not confident it's color?!)
any clue would help me much !!
