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! David -- David W.

Martin c/o The OpCode Factory tm Seabrook, Texas, USA > UUCP: davidm@sugar.hackercorp.com 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. Jonathan Bernstein jbernstein@eagle.wesleyan.edu

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. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "What works for me might work for you" -Jimmy Buffett

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. > All this long and short, odd and even frame nonsense >I don't know all that much about.

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. -- VAX Headroom Speaking for myself only... blah blah blahblah blah...
