This is not a false statement.  When I refer to NTSC, do you even know what I 
am saying?  This is a broadcast "standard".  I am not saying that Amigas
are not NTSC compatible, just that their output does not fully implement ALL of 
the NTSC standard's capabilites.  For one: COLOR.  Unless you are still watching
the Simpsons on your 9" b&w, you must already know that NTSC supports more
than 32 colors!  Even if you try to counter this with HAM mode, your 
resolution gets even poorer than NTSC.

For your information, the only Amiga that has ever had color in its NTSC
"COMPATIBLE" output was the A1000. The rest have ALL had monochrome composite
and analog RGB NTSC "COMPATIBLE" outputs.

Remember, NTSC is a TELEVISION standard, not a computer monitor standard.
It just so happens that our GREAT "Amy" uses most of the same hardware
timing standards.  Of course this wasn't by chance, someone made the 
smart (IMHO) decision to do this.  BUT, this is also why we have flicker
when displaying single pixel lines.  TV doesn't really have the capability
to display single pixel lines as precisely, so the lines tend to be fat and 
non-flickering.

If you had just woke up from that sleep 5 years ago and read some technical 
papers/books on NTSC standards, then you would have already known this and 
not wasted both our times. 8)
