I recently came across some text concerning a "graffiti" display board.
Considering I saw it on April 1st I'm wondering if it's a prank?
If it isn't a prank.. I have a few questions:
It sounds alot like HAM-E or more recently the Video-DAC advertised by
Power Computing.
Q. Will this board feature RTG and/or emulate AGA on ECS amiga's?
If I could get a board like this for $100 that turns my ECS machine
into an AGA compatible system, I'm THERE with the cash :) I already
own DCTV and HAM-E.. but would love to have a LOW-PRICED system
capable of RTG as well as AGA emulation on ECS machines.
Also, I noticed from the technical info below that it only allows
256 colors out of 262,144. I wonder why there are no HAM modes
(I guess HAM8 emulation is out?) and why there isn't a full 16 million
color palette?
Is it a prank? Or is it for real? Any more info on this board?
Any answers to my questions?

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 successfull=
y=20
tested!
- 256 out of 262144 colours at a time=20
- lores Output on OCS/ECS Amigas, Hires on AA Amigas. Overscan and=20
interlace supported!
- simply plugs to the RGB-port of the Amiga. No need to open
the Computer! (RGB 15Khz Monitor required).
- 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 =3D> 4 DMA channels=20
=3D> 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 and 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
