I am looking for good CRT controller for EGA graphic.
64 colors palette 3 RGB double lines 2 bits each one. Format: RR-GG-BB

I have found this one: UMC UM6845

Is it good chip?
How it can be connected to TEA 2000?

I would expect special 6 lines for it: 2-2-2
How to connect RA0-RA4? If someone could explain what exactly these lines means?

How to achive vertical_blanking.
I have attached TEA 2000 docs.
