#flickerfixer vs. a2320
35 messages in this thread
does anyone know what, if any, advantages the new a2320 video card has
over the microway flickerfixer? is there some extra support for the ecs
and new graphics modes?
i have an opportunity to buy a used flickerfixer and zenith flat screen
monitor, so any comments on the monitor would be greatly appreciated, too.

The 2320 does scan doubling for lores (200 line) displays so there are no
motion artifacts in these modes, unlike the FF.

what the heck are motion artifacts?

When high speed animation is happening, there is a ghost left by the moving
object. That is an example of motion artifacting.

Ben,
I would have thought that both the 2320 and the FF line-double the
200-line mode, which would mean that they both should have those artifacts.
What am I missing?
Karl
the FF buffers two screens even on lo-res, that causes the artifacts. The
2320 only buffers 2 screens in interlace, and in 200 line mode jjust
repeats the previous line again (so it still is at 60 frames per second).
Woala no artifacts in lo-res(200 line mode).

Ben,
i'm not familiar with motion artifacts in lores, could you explain it?
—Andrew
When Hispeed sprites, or anims run in 200 line mode they leave a ghost.

A wider overscan mode, works with the new ESC chipsets, works with
both PAL and NTSC machines, costs less.
Don
Don,
when you say it works with the new ecs, what does it do that the ff
doesn't, which would make me want this product over the ff? if i use the
ff instead, will i be limited in what new graphics modes i can use?
—Andrew
AJ,
Read message 4534…that will give you a quick overview of the
differences.
Don
You cant switch between PAL and NTSC with the FF. Thats important if you
like to use any European software (like those neat demos and games).
Nick
Do you know anything about Flicker Free Video from ICD? I think they are
very similar to the A2320.
Leslie,
I know nothing at all about it…sorry.
Don
Leslie,
I saw FFV at AmiExpo in L.A. It is a little board that is inserted under
the Denise chip (i.e. remove the chip, plug the chip into FFV board and
plug the board into the Denise socket.) It supports monitors with 9 pin
connectors and is supplied with a 15 pin adaptor for VGA monitors. In NTSC
it supports 832 X 480 lines and 832 x 568 in PAL. It supposedly presents no
conflicts with any Genlock.
I saw the display on it. Very nice. I asked if it was ECS compatible and
they said yes.

Wayne:
One area of possible contention with FFV is if you plan on using DKB
Software's MegAChip 2000 board to give your 2000 2 megs of chip ram. The
board sits in the Agnus socket, and sits over the denise socket, so it'd be
impossible to use both FFV and MegAChip 2000 in the same machine. I just
sold my FF, and ordered a 2320 board from C= and as soon as I get it in,
I'll pull the FF and deliver it to it's new owner. I think FFV is also
slightly over priced. <IMHO>

Mike,
I think FFV's price was baseed more on the FlickerFixer price than on the
engineering costs, parts and potential market (unless it was anticipated to
be a market of less than 200 pieces or so…) but when there is only a
little ccompetition you only need to beat them a little. Some people
probably think it is worth the price to save the video slot.
BTW, I keep seeing these messages about the 2320. Is there a file here
that describes it? Also, thanks for the info about the FFV/DKB MegaChip
physical conflict. Any possible workarounds like stacking sockets?
wmc
Wayne,
Have you asked Dave Minnich about a description, etc., for the A2320? Since
he is Commodore's representative here, he's sure to have the real
information. GO CBMSER to find him.

Actually, it is a very expensive board to make. It uses almost all surface
mount components, many of which are, unfortunately, difficult to get at
this time. Not that we should have a problem getting them; we just won't
have much of a choice where to get them.
Having seen it at AmiExpo, I wish to back you up – it *is* a very nice
piece of hardware. .Very professional and very neat, in the physical sense
of the word. Good work.
BBS->Williams.Ben[AA7AS]
Thank _you_. People sometimes don't realize that it would be a lot cheaper
for us to make (and sell) if we made it a big card that plugs into the
video slot. Doing those tiny, packed, surface mount things isn't easy.
Yeh, I know. :^) We make a PCB layout package, you know.
BBS->Williams.Ben[AA7AS]
I was really wondering how FFV compares to its competition. I have, and
still use, ICD products (Atari 8-bit stuff) and I've had little problem
with their products (stuff like a couple burned condensers after several
years runninng a 24 hour BBS) and NO problem with the company. I trust
their stuff but haven't tried any of their Amiga products. Is FFV actually
on the market? Excuse the question, but, people are talking about The
Toaster like it's been around for years and you still can't buy one!
FFV should be available for sale at the AmiExpo in Koeln this weekend.
Craig
Leslie
I believe FFV is available now.

That overscan number is what it is _capable_ of. It is won't produce
images bigger than what the Amiga will, which is less. If you have any
specific questions, ask away. Or leave me your address in email and I will
send out some info. Craig
Craig:
I REPlied before, but I think it got lost. The question was…
I have an Advantage 2000 with a Quantum mounted on the card ( it
came that way ). I ALSO have an external SCSI drive, but when attached to
the pass-through at the end of the card, with the proper cable, the
Advantage does not seem to recognize it. Hmmm… do I need to change
jumpers or something like that?
Weird, but I would appreciate some comments.

You need to change the SCSI ID of one of the drives.
Craig
Craig…
Thanks for your reply and Mail, but…
Do you ( or anyone reading this ) have any tips about how to go
about this? Data…
Advantage 2000 SCSI HOST ADAPTER, QVP 40 mounted on the card.
Pass-through for SCSI at the rear. EXTERNAL SCSI Controller/Drive combo (
sold as C Ltd AM-24 ) which is in its own enclosure. What switch r junper
should I alter?
By the way, "SCST_LISTER" shows that a QVP exists on ALL device
units (0 – 6) weird.
Charles Conlow 74116,3067
What kind of controller is in the C Ltd box?
Craig
The Cltd AM-24 drive(s) were mostly Okidata 20MB clones of Seagate 225's
with an Adaptec ACB-4000 ST506-SCSI converter.

I had an AM-24 myself until last week. The SCSI ID is set by the DIP
switch(es) on the back of the drive. Most likely yours are all-three set to
OFF which means SCSI unit 0 (zero), OFF-OFF-OFF is binary 000 which is (!)
zero. If your other drive is set to zero as well (likely) you will want to
config the AM-24 as 1 or some other ID. Set the leftmost switch to ON and
you're SCSI unit 1 (OFF-OFF-ON is binary 001 which is 1).
I am purposefully vague (sorry) about orientation for that "leftmost" (e.g.
looking at front or back of the AM-24) 'cuz I forget which it is. If its
not UNIT 1 you will have set is as unit 4 (ON-OFF-OFF is binary 100 which
is decimal 4)… which should also work.
Are you trying to run the Advantage controller AND the CLtd controller ?
either one should be able to handle 2 (7 max) daisy-chained SCSI drives and
having the two controllers on line could screw things up since the SCSI
host(s) sometimes "grab" one of the UNIT ID's for themselves and may also
conflict. I ran the Cltd controller, plus AM-24 together with my new Xetec
controller OK, but…
If my answers are unclear please clarify your complete Hardware config
(500,1000 or 2000, etc) and I will try to followup.

I'm E-mailing my address. I look forward to reading about you Amiga
products.
