There is a setup utility to install cygwin from internet available at this link.
For printing you may want to install ghostscript and use the ps2pdf facility
to convert from .eps output to .pdf Format. Use -YXf 0 unless your
astro fonts would match what is needed.
The source code is available back at the main page
The fonts used by this kastrolog.exe are available here
I am interested
to include more fonts in similar quality for the asteroids in the future
