I patched ITS to restrict BLKO pointers to the range 777000,,0 -
777777,,777777.  Now SUDS starts with no apparent problems.

Yet the display stays blank after I load a DRW file.  I'm not sure it's
supposed to display something or if I have to do something else to paint
the screen.  Back to reading the manual.
