The real changes would occur in the graphics.library . One option is
to make a retargetable graphics library, referred to as RTG.lib by some of
its proponents. The lib would simply supply certain programs with
different jump table offsets, specifically those programs that could use
the new graphics board. Old progs get the old jump offsets and everything
works the old way. If you don't have the gfx board, you don't have RTG.ib
and everything's cool.
