Fresh from the omnipresent `reliable source,' I have garnered the following hot and spicy rumor (so good, it's bad): Commodore has, ready for sale, a de-interlacer/scan doubler for the 2000/2500. Price $295. I honestly trust the source, who says he recalls the name of the beast to be the A2320 (but that could be incorrect). He even called someone at C= to verify this rumor when he heard it, and was told it was available a couple of days ago. He was further informed that it did not take up the video slot, though the way it avoided this was unclear. Anyone care to (respond to|back up|refute|complain about) this? I would be fairly happy were this the case. The price seems close to reasonable, depending on the street price, and I guess it will go on the educational discount list. But, is it correct that I cannot buy this board through the ed. program alone, that one must purchase a CPU with any order? I did buy my computer through the ed, program, but I did so months ago. If this is the policy, has a decent explanation of it been given?

Seems odd to me, too. I fail to recall ever having heard a true rumor about
the Amiga from some source besides c.s.a, long before c.s.a got its teeth
into it.

At least one of the people my friend talked to muttered something very
befuddling about an external video connector, or some such nonsense. I
hypothesize that this particular person has a monitor port and a video slot
confused.

What I guessed. I have now talked to someone who has sold this beastie,
though not in the US. My dealer called to order a couple, and was told that
everyone was off at a sales meeting. I guess that means everyone is gonna
get fired again in C= sales and marketing...isn't that what sales meetings
are for at Commodore?

The US price is suggested to be $299. This is basically the same display enhancer circuitry as in the A3000 but as a plugin card for 2000 owners. You should be able to get them from the dealers when they get the sheets. Also, AmigaWorld magizine will be running a review of the A2320 in a future issue - so life gets more interesting again!!

I was talking to the Australian marketing manager for C= on Wednesday (A3000UX release demo), and she knew nothing of th A2320, and said that just because it was being released in the US did not mean that it would ever make it over to Oz. Also, are there 2 versions of the card, a PAL one and an NTSC version? Could somebody post the specs or email them to me or something?

The answer to this may be obvious to everyone but me but here goes anyway. Does this thing (A2320) work in BOTH ntsc and pal modes? I have a PAL machine but use it in NTSC mode from time to time. I do have a multi-sync monitor (NEC 3D) so that is not an issue. Before I buy one in the US I want to be SURE it works on my PAL system.

The A2320 is a video slot card (half card in size, same size as the MicroWay FlickerFixer as well as most other video slot style cards). This card has not gotten alot of press due to other cards and machines that Commodore has recently rolled out, so even some of our dealers and sales people may not know about it just yet. The US dealers should be getting their sales information inside of two weeks (just in time for Christmas!) so keep bugging them about it if you want one (and I hope you all want one!). Enjoy!

First, the A2320 has FULL overscan support for BOTH PAL and NTSC displays (768x489 for NTSC and 768x576 for PAL), then there is the automatic switching of de-interlacing of interlaced images to when in interlace mode to scan-doubling of non-interlaced images when in non-interlace modes that results in NO video artifacts (ghosting or smearing) which is a real plus for scrolling display, games, etc. There is also automatic genlock support (both for NTSC and PAL genlocks) such that if an external genlock is connected to the Amiga (and is meets our guidelines for how a genlock should interface with the Amiga) the A2320 will de-interlace the Amiga's reference RGB output to provide a flicker free display. The A2320 also works with the new ECS graphics modes such as the `Productivity' mode by automatically sensing this mode and bypassing the Amiga generated 31.5Khz video to the multiscan monitor connected to the A2320's video output connector. This allows the A2320 to work with this mode without moving cables or removing the video card as you might have to do with the MicroWay product. The card also has a user controlled bypass switch that allows you to manually do the bypassing of the video data for the ECS `Superhires' modes or any other graphics modes that you desire to bypass to the monitor. This also allows you to do a before and after enhancing effect so you can see what a difference the A2320 can make on your graphics screens! The A2320 also can automatically switch between PAL and NTSC video modes so that the card can more fully support AmigaDOS 2.0. The lower cost is due to the very high intergration of the AMBER gate array and the special video memorys that only recently have become available. I hope that this answers your questions, and sorry for the sloppy typing!

Yes, the A2320 does exhibit the same top 1/3 scan line flicker as the A3000, but with the Commodore 1950 multiscan monitor (and some others) you can adjust the vertical and horizontal sizing controls to put the black boarder behind the monitor's faceplate and not see the top line flicker.

Sure, it works, but if one uses full vertical overscan, then the top
corners of the display disappear behind the rounded corners of the bezel. The
1950 doesn't, as far as I could tell, have a proportional horizontal size
control that would allow the picture to be narrowed just enough to make up for
this. The horizontal size switch is much too coarse an adjustment. In any
case one shouldn't have to fiddle with knobs to make up for an inadequate
deinterlacing algorithm.
If, as has been suggested, this top scan line flicker is an artifact of
NTSC, there must still be a way to overcome the problem, since the flickerFixer
does not behave in the same way. Perhaps it throws away the first scan line in
every odd field. This would seem to be a reasonable solution, and I wouldn't
expect the marginal cost of the extra logic to do this to be large, though I'll
certainly defer to the opinions of people who actually design these things.

That's fine for the workbench, but what do you think happens when some
program comes along and opens a custom screen without looking at the prefs?
You guessed it.
Every time this subject comes up, I ask why the C-A deinterlacer can't
handle the first scan line in whatever way the flickerFixer does. I've never
seen any answer to this. I'd just like to know whether the problem is due to a
design or manufacturing error, or is the deliberate result of some cost
reduction measure. In either case, is it with us forever?

Fine. That's what the interlaced output looks like. Now tell me why
the DEinterlaced output has to look like that. It's not going to an NTSC

I'm not sure I see your point here. To get rid of the flicker all you
have to do is suppress the RGB signals that light up the dots on the screen
during the first scan line of the odd field. You don't have to touch the synch
signals, which are what you're describing. All you're doing in this case is
throwing away some information that's useless anyway because of the flicker.

Yes, but what does the electron beam scan have to do with the problem? Whatever happens to the signal at the monitor isn't causing the 1/3 line flicker, the de-interlacer is. That means that the timing in the A2320 doesn't sync every frame until about 1/3 of the way into the first scan line. The lack of sync causes a variation from frame to frame that results in oposing information appearing as flicker. Obviously the FF overcomes this by syncing earlier or (more likely since I talked to the FF guy and this seems to be his technique for eliminating problems - i.e. garbage on the right edge) just covering the offending video with blanking. A similar solution for the A2320 would be reasonable (BTW, the FF displays "about 719 by 479 hi-res pixels", I wonder why :-). Rick Tillery (drtiller@uokmax.ecn.uoknor.edu)

The problem is with the way that the Amber chip did the de-interlacing. It has nothing to do with beam position or sync or any other such infromation, but these are not unreasonable guesses! When the Amber chip was in development I did not think that this was such a bad artifact (I know, I know, how could one be so foolish!) and only a few people said anything about this flickering 1/2 line. By the way, it really is 1/2 of the total 910 (NTSC) or 908 (PAL) line, that is flickering, because of the position of active video in the line it appears to be only 1/3 of the line. It is possible to fix this `artifact' by changing part of the internal circuitry of Amber and work is under way to investage this. I can not say much about this for may reasons but your concerns are not going unheard! When it is appropriate for me to make further comments about this I will do so. Remember that most things are not cast in stone!

First off: I got my 2320 last week and after a week of use, I can say it's a decent board. I wish these people would quit complaining because a small portion of ONE line out of > 500 flickers a little. If you crank up the vertical size, you can't even see it! Heck, I got the thing for $100 less than a flickerFlixe. One question: (to Scott Wood, preferably) I'm using a Mitsu Diamondscan 14" with my 2320 and I cannot get the thing to expand it's horizontal size enough to get rid of the black border around the screen. It looks kinda bad compared to the 1950 (but appears sharper with better color saturation; sorry :-). Any advice on this one? (Take it slow: I'm a software guy...). Thanks...

This is necessarily a reply directly to Scott. When I first heard
of the release of the A2230, I thought, "Great!, and look at the price!"
Now I'm wondering if it is so great. Is the general conensus that the FF
is much better than the A2230? Is this flickering problem ONLY on the
first scan line or does the whole screen flicker a bit? Are there any
other known problems with the A2230? What about colour etc...How does the
actual picture quality compare with the FF (should be exactly the same, I
know. I'm just making sure.)?

It is present in both NTSC and PAL interlace modes but not the non-interlace screen modes. The A2320 supports all 4096 colors of the Amiga, as many colors as the Amiga is capable of generating, which of course also works with the `Dymanic HiRes' modes of the Newtek (TM) Digaview device. As for picture quality there should be no differance, only more functionality for less money. I hope this helps!

In questions about which is better, the FlickerFixer or the 2320, the 2320 will properly handle X-Specs. This means you can get LC 3D on the Amiga with the scan lines filled in, which looks much better. The FlickerFixer, although it handles the first scan line correctly, does not work with X-Specs, or any other LC 3D multiplex scheme. I have a FlickerFixer and had to wire up a switch box (another $50) to switch between Amiga Video and FlickerFixed Video. So, for those interested in stereo 3D on the Amiga, the 2320 is your best bet. John

In-Reply-To: message from clemon@lemsys.UUCP The top scanline "problem" doesn't happen on the flickerFixer because it can't handle screens of 480 pixels high. The top line artifact isn't found in just the Amiga. In my RTV class, all of our camera and studio moniters display the same thing. The moniters show you everything that goes on-air without borders. Viewers would never see this, just as they'd never see it in recorded Amiga screens. I still suggest having your menubar set one pixel down from the top...you'll never notice after that.

This may effect the 3-D effect since the LCD glasses open and close their shutters at the field rate and expect each field to be DIFFERENT and not de-interlaced together.
