-
- No.
-
- From the information I have, this is not a graphics card.
-
- It a graphics adaptor, along the same lines as the HAM-E and DCTV.
-
- It plugs between the RGB port and the monitor.
-
- You might want to try contacting sysop@nostlgic.tng.oche.de for more
- information.
-
- A clipping of information I have received:
-
- Some technical information about the Graffiti card... - works with _any_
- Amiga:
- A500/1200/2000/2500/3000/3000T/4000/4000T
- Even A 1000, CDTV, SX-32, SX-1 and A600/A500 plus have been successfully
- tested! - 256 out of 262144 colours at a time
-
- - chunky graphics for fast animation sequences/ texture mapping games
- Chunky means: one byte in memory represents one pixel on screen. -
- programmers only have to switch on 4 bitplanes => 4 DMA channels
- => full 7MB/sec on AA Amigas!
- (compared to 3.5 to 5 MB/s on 8bpls lores!) - faster display by reducing
- the resolution:
- The Graffiti supports half and quarter-lores (160 an 80 pixels/line)
- without additional CPU or blitter time for expanding the pixels! - uses
- chipmem to store graphics, no memory on the card (that's why it's
- this cheap!) - sales price 149 DM (about 700 DKK, 105 US$) - software:
- + external video driver for shapeshifter shipped with the card
- + IFF/GIF/JPEG viewers
- + AVI Video player
- + doom-style games
- + Graffiti support CD released every 3 to 6 months:
- only DM 9,95 (40 DKK, 7 US$) - for the developer Manual write to

- 1. What it does Graffiti changes the Amiga bitplaned graphics into a
- chunky pixel mode. I.e. one byte in memory represents a single pixel.
- The value of a byte selects it's colour. The colour palette is 256 out of
- 262144 at a time. Possible resolutions are 640x256 (hires version only),
- 320x256, 160x256 and 80x256. In each mode, 256 colours are available,
- interlacing doubles the vertical resolution. 2. How to connect The
- Graffiti card plugs into the RGB port of the Amiga. The monitor must be
- connected to the RGB output of the Graffiti, there's no need to open the
- computer. See appendix A for Dip switch settings. 3. System
- requirements, compatibility, limits The hardware has been successfully
- tested with all known Amiga models: A500, A600, A1200, A2000, A2500,
- A3000, Amiga CDTV and the A4000. Even "the" Amiga (later called the Amiga
- 1000) has been sucsessfully tested. For displaying the output, a standard
- 15khz RGB-Monitor like the commodore 1081 and 1084 models is required.
- The commodore A2024 is not supported. The Graffiti is PAL and NTSC
- compatible.
