Individual Computers: new product Indivision AGA
« on: July 26, 2008, 12:11:48 AM »
During the 80s, it was common use to build computers in a way that they can output their picture on a TV set. This was done in order to reduce the overall system cost for the user. TV sets work with lower frequencies compared to today's monitors, therefore the picture flickers. A flickerfixer converts the signal in a way that a modern VGA monitor or TFT-display can be used. The name flickerfixer was mainly created because the problem of a flickering picture is solved. We've already had a very successful product called Indivision in 2002. It was connected to the monitor output of the computer, but it has been sold out in 2006.

Flickerfixers are in high demand. One unit of our external flickerfixer Indivision has been sold on an internet auction platform for more than 900 US Dollars in march of this year. That's more than four times the last retail price! The popularity and stability of value of our products cannot be proved any better. We have already started development of a new flickerfixer in november 2007, which is finished now.

The first flickerfixers for the Amiga have already been available 17 years ago. Since that time, all flickerfixers - including ours - have been using the same principle: The picture frequency was doubled. This is not enough for most modern VGA monitors and TFT-displays, as the picture of a computer with PAL standard was only displayed at slightly less than 50Hz. Most monitors require 60Hz or more these days.

With Indivision AGA, we're striking a new path. As the name suggests, it's a flickerfixer that is very closely tied to the AGA chipset. This could only be realized by putting the flickerfixer inside of the computer. The product is mounted over the Video-Chip "Lisa". The VGA display is connected directly to the flickerfixer. Further connections are not necessary.

Listing all features of the flickerfixer would go beyond the scope of this news item. You can find the complete technical data in this PDF-overview. The outstanding features are:

    * 24 Bit colour resolution in all screenmodes
    * support for super hires modes
    * Highgfx support up to 1024x768 pixels
    * all screenmodes can be displayed at 60Hz or more
    * no adjustments necessary

Two options have been added for retro-gaming enthousiasts that allow a step-by-step approximation to the display of an old TV set: Vertical syncrtonisation allows reducing the output frequency down to 49.9Hz, which will eliminate tearing-effects. In addition to that, a scanline-emulation can be switched on. This will emulate the dark lines between the scanlines of a TV screen.

Development and production of this extremely complex product is very expensive. Our trade partners, who have been serving the Amiga-market for many years, have made considerable financial contributions to the production. To account for that, Indivision AGA is exclusively available only from these resellers until january 1st, 2009: (alphabetical order)

    * AmigaKit (England)
    * GGS-Data (Sweden)
    * Software Hut (USA)
    * Vesalia (Germany)

Production has already started, the flickerfixer will presumably be shipped to our tradepartners during the first week of september. The suggested retail price is 129,- EUR including 19% VAT. Only a version for A1200 computers will be available at first. We're already working on a version for other Amigas with AGA chipset.

The following pictures show the prototype and screenshots where colours are not displayed correctly. The actual product may vary.

16mb of framebuffer!? Jens, you madman!


Can't buy any smaller chips these days. It's a waste and a saving at the same time, although only about 2,5 megabytes are actually used.

I could have gone for smaller chips, but it's almost certain that they will be phased out during the next year. The old (external) Indivision design suffered from using lots of chips that are unavailable these days. This new design is only based on parts that are available, RoHS compliant and most of all: affordable.

Compatible with the Video Toaster?


Sure, the Video Toaster is very advanced over other genlocks, but on the Amiga-side of things (chipset behaviour), it's the same as most other genlocks.

I'm aware that many TV studios in North America still use the Toaster. I'd be a fool if I didn't make sure that my stuff is compatible.

I never owned a Fast ATA, but the kickstart sockets are completely free. Indivision AGA is extremely flat, but you might need a spacer (additional socket between board and FastATA).

I'm not exactly a one-man-army any more. This product has been developed together with Oliver Achten, who is also on the Clone-A project. We both have gained so much knowledge about the Amiga chipsets that we can help each other.

Consider me the "architect" of Indivision AGA: I have done the concept and the basic would-this-be-possible-calculations and after that was positive, I started explaining it to Oliver and made a prototype board. Oliver then implemented the logic, so this is yet another co-production of our brains.

The nice thing is that we're really thinking alike. Plus, we wouldn't be true friends if we couldn't take an argument. The good thing is that we always keep a certain level of professionalism, so even an argument comes out productive. Not sure how to translate this, but "culture of conflict management" or "clear the air culture" might describe it good enough.
