It grabs 4 bits per pixel, period.  It has hardware contrast/brightness
controls instead of software.

It grabs a field at 4 bit planes in 1/60ths a second, a frame (two fields)
in 1/30 sec.  It will grab a still frame out of a moving video.

No, not with the current software, since it's all B&W.  The promised 
NTSC to RGB converter would seemingly support HAM if the accompanying
software does.

Yes, it comes with the C code to read frames.

It's best feature is the ability to go on "automatic" and grab a series
of frames (until you run out of RAM).  You put your VCR in slow mode, and
you can get a nice sequence.  I'm hoping they'll add the ability to multi
grab in a mode that does 1/4 screen frames, or even 1/9, 1/16th etc.
so I can grab bunches of frames that were designed to be reduced anyway.
