I forgot to implement your tip of using the exact camer aspect ratio of
2*cos(pi/6)/1. Here's the corrected code. Thanks again for your help?

camera
{
 #local CameraDistance = 10;
 #local ScreenArea = sqrt(2*pow(1,2));
 #local AspectRatio = 2*cos(pi/6)/1;
 orthographic
 location -z*CameraDistance
 direction z*CameraDistance
 right     x*ScreenArea
 up        y*ScreenArea/AspectRatio
 rotate x*asind(tand(30))
 rotate y*45
}

plane
{
 y,0
 texture
 {
  pigment
  {
   checker color rgb 0, color rgb 1
  }
  finish
  {
   ambient 1
  }
 }
 scale 1
}
