	Here's HAM-E.

	It doesn't change the format of the output signal, takes
RGB and outputs RGB.

	You have two modes. One is 256 (or is it 512?) out of
16.7M. The other is a HAM style mode giving 241K out of 16.7M
simultaneous. The fringing isn't really visible like with HAM
because you have 256 registers to choose from.

>	3) Amiga-co-operative ?

	The way it works it that in the upper 1/4 -- 4 scan lines
of the display it encodes some information that, when the HAM-E
board sees it, tells it to convert the image. So you can use any
player programs. The images are just IFF files.

>	4) Resolutions ?

	384x480. Plus, there is a higher version of the board
which does anti-aliasing to give you the equivalent of 768x480
without any additional bus usage.

>	5) Genlockable  ?

	Yes, any genlock that connects externally via the RGB
port will work just fine.
