Thanks peter , I'll take a look although I've seen is for =

handling a NTSC TV signal.  I'm mainly insterested on the =

HGC (Hercules Graphic Controller) kind of signal.

What I'm looking for is something like what is explained in =

page 16 to 19 of the MC6845 datasheet (link below).  This is =

a CRT Controller with memory interface and much more.  I =

want to replace its work with a microcontroller and RAM.

http://www.datasheetarchive.com/pdf/2272869.pdf

The datasheet is not very clear and I will like to know if =

someone knows about a more didactic link about the subject.
