"Sliced HAM" (or, "SHAM") is a trick used on a HAM-mode screen to give the
illusion of better pictures.  In a normal HAM picture, the palette of 4,096
colors is set, and then a single register (R, G, or B) is changed from one
horizontal pixel to the next.

SHAM pictures modify the palette to a NEW 4,096 colors for every scan line,
so colors from one scan line to the next have a larger variety of colors
to choose from.

To be honest, I can't see much difference between SHAM and HAM pictures, but
as long as there are pictures in any format that I want to view, I'll keep
getting the viewers for 'em.
