Hello,

    I doubt that there are no information in full explanation on any website 
existence.  Fortunately, Understanding the Apple II+ and Apple //e have full 
explanation in chapter 8 how Apple II video work.  It is easier for me to 
understand when I read it.  It can be complicated when I want to understand 
how C64 work.  I do know that 640x200 on NTSC will not work with color 
reference 3.58MHz.  I wonder how C64 can overcome this problem.  I would be 
interested to learn C64 video circuit.
    Earlier post shows that Understanding the Apple II+ manual is available 
in PDF.
