/*
 *	Vectrix 384 driver - works with tandy color printer as well
 *  in reverse printing 8 color mode.
 *  This doesn't work on Vectrix 128 because it redefines the
 *  color table. It can be hacked to work on the 128 by changing
 *  the colours but then it will probably not print best. The color
 *  table is purposely designed so that it will print well
