This Zoo archive contains three files:

Hi-C:  A conversion program that creates a 640x400 screen from
  4 320x200 HAM IFF picture files.   The resulting picture is made
  to represent the HAM color spectrum by reloading the color palette
  for each scanline.  
 Syntax:  Hi-C upperleft.pic upperright.pic lowerleft.pic lowerright.pic

HiShow:	A show program to view the Hi-C's output file.
 Syntax	HiShow hi-c.output

4Pics:	A Hi-C output file.

Hopefully, I can improve the color palette determination to make the 
  16 colors more reasonable match the input ham pictures.  It is advisable
  to use pictures with approximately identical colors side by side and
  it is preferred to use HAM pictures where color changes run vertically.

  It would be very possible to have clean pictures if some consideration
  is given with picture selection, I didn't here to emphasize the problems
  inherent with such a system.
