When you use the MS-DOS version 5.0 or later QBasic SCREEN command to set
the screen to mode 13 (320 x 200, 256-color resolution) on a Tandon Laptop
386 with a VGA card, meaningless characters may appear on the screen. When
running in this mode, the VGA card ignores requests to set colors;
therefore, anything displayed on the screen appears in unpredictable
colors.
CAUSE
This behavior is caused by a problem in the VGA card itself, not the
machine, monitor, or Qbasic.
