don't know much about this question.

using a 68010 (direct plug in replacement) will get you around 10% improvement
overall.  integer multiply/divide instructions run around 30% faster, and
tight loops (memcpy, strcpy, strlen type things) run 100% faster.

yes, but the results can be unusable.  in the amig manual, find the 23-pin
video connector pinout.  use the DR, DG, DB, and DI pins (and of course
the HSYNC, VSYNC, and GROUND pins!).  you'll only get 16 colors, and some
programs will be unusable because they use foreground and background colors
that map to the same RGBI color.
