Flickerfixer for Amiga 1200 Computers

Indivision AGA Mk2 A1200/4000T
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 (aka de-interlacer)
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. Individual
Computers 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 since 2006.
The first flickerfixers for the Amiga have already been available
17 years ago. Since that time, all flickerfixers 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 50 Hz. Most monitors require 60 Hz or more these days.
Indivision AGA goes a new path. As the name suggests, it's a
flickerfixer that is very closely tied to the AGA chipset. This could
only be achieved 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.
Indivision AGA's most notable 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 60 Hz or more
- no adjustments necessary
Two options have been added for retro-gaming enthusiasts that
allow a step-by-step approximation to the display of an old TV
set: Vertical synchronisation allows reducing the output
frequency down to 49.9 Hz, which will eliminate tearing
effects. In addition to that, a scanline emulation can be
switched on. This will simulate the dark lines between the
scanlines of a TV screen.
Please note that the Indivision AGA 1200 can only be used
with an Amiga 1200 computer, it won't fit any other model.
