Read the source code to Sqrxz.  It's pretty commented.

Double buffering is a pretty simple concept.  Pick somewhere in memory for
the double buffer that's 1024 bytes.  _plotSScreen is ideal, since that's
pretty much it's purpose.  You must draw everything to the double buffer,
and at the end of each frame, copy it all to video memory ($fc00) using an
ldir instruction.
