[comp.sys.amiga.misc] CBM Support is GREAT!

ALL:
  Recently I had the pleasure of getting a hardware extended warranty
from CBM for my Amiga 2000 that had expansion bus problems. Thanks
to the folks at Commodore I got an extended warranty and a new A200
-0 motherboard. User and computer are working wonderfully!

Hmm.  Does anyone know what C= plans to do about the A3000 problems
(specifically the deinterlacer's flickering black line)?  Is this a bug
that they will fix or is it a feature?

	I have to agree with David about CBM's customer support department.
Late last year I had to have my motherboard replaced. When I returned to school
my machine with its new motherboard no longer worked. I attempted to go through
my dealer to resolve this problem but I discovered that he had sold the store
and that they were no longer authorized to repair Amigas. I phoned Commodore
and Spoke with one of their support representatives and with the department's
President.  They had UPS come to my school to pick up my machine and they then
sent me A BRAND NEW MACHINE, overnight no less. Thanks, CBM.

Technically speaking, it's a feature.  Converting a full NTSC frame the way
the A3000's Amber chip does it is just guaranteed to give you that flickering
1/2 line.  That's an effect of the NTSC standard and the way its different
frames get displayed.  All this long and short, odd and even frame nonsense
I don't know all that much about.  It might be possible to fix, I don't know
if they're planning to or not.  It would certainly require a revision of the
Amber chip to accomplish.

No Dave, NTSC has nothing to do with it.  Don't believe everything
you hear.  An interlaced field has 262.5 horizontal intervals which
become 525 unique lines at twice frequency.  With a static image
there is no reason for these lines to change.

What is clear from the presence of this artifact and the much more
serious one which is visible when Amber is used with the non-ECS
Denise is that the system was designed on the assumption that it
would be blanked by the monitor bezel.  The A1950 is able to do this,
but it is one of the very few monitors which can.  The "standard"
for all computer displays other than those derived from television
is that the margins are blanked electrically.

A bit more concern for compatibility with third-party hardware
would have avoided both this problem and Amber's other serious problem
of genlock incompatibility.  The A3000 is supposed to move Commodore
into new markets; success in these markets will require some new
attitudes toward standards and compatibility.

It would be nice if it were fixed, but its not that bad of a problem (for
me anyway).  I just adjust my monitor so that that line is not visible
behind the plastic border of the monitor.  Of course this requires a
monitor that does overscan, like the 1950.  I tried several monitors
while waiting for my 1950 to arrive and they all had that iky border
around the usable display space.
