Wrong! Dynamic HAM has 16 (or maybe it *is* only 12 or 13) color 
*REGISTERS* per scan line. You use those registers inconjuction with
HAM to come up with many more colors, just as you use regular HAM, which
has 16 color registers per *screen*

At least this is how I understand it works from what I read in my 
Digiview 4.0 manual.

I digitized some regular HAM pictures (in low res) and then displayed them
in the low-res Dynamic HAM mode (DynaHam works in low and High res) and
it did not lose anything but the fringing. The edges were much sharper.

It is painfully slow tho.
