[Thank you Alex M. & Peter K. for previous answers in this discussion]

    Background: I want to display some large 256 level greyscale
 video samples. The standard Amiga will output only 16 levels.

    So, I am trying to figure out the best way to increase the number of
 greyscale levels viewable on the (my) Amiga. So far the candidates are:

    1) Dithering
    2) GreyScale to HAM  [SHAM, SHAMM, Dynamic whatever]
    3) A colour board

    Are there any other options?

    Has anybody written an n-bit sample to dithered bitmap routine?

    Will HAM (and dynamic brethren) be any use?

    What greyscales do the popular 24 bit boards put out?
    (ie. DCTV, ColorBurst, HAM-E, A2140, Firecracker 24)
