286Stars

Category: Christmas Challenge
System:   286 PC, MS-DOS
Language: Assembler
Len source code: 275
Len exe file:    30
Len code only:   30
Instructions:
  I used PCem for the screenshots. But DOSBox will work fine.
Description:
  This draws diagonal lines in one direction and then mirrors them to
  complete the image. Some bytes are saved by depending on the startup
  register values (hence the MS-DOS requirement) and by scribbling all
  over off-screen video memory.
