- As far as I know, the principle they use is quite like the old 'HAM-E'.
- Maybe you remember the 'DCTV'? Encoding colors for a lowres-screen in
- hires-formats, thus getting twice the number of bits for every pixel on a
- screen. 'DCTV' did this analogous, giving a composite signal, but a
- company named Black Belt Systems used the same system digitally, giving
- RGB output in 65536 out of 262144 colors (by heart, I'm not sure...)
-
- AFAIK, 'graffiti' uses a similar system, encoding colorinformation for
- one 'grafitti-pixel' in more AGA-pixels. No higher resolutions, just more
- colors with fewer bitplanes (maybe even chunky modes...)
