PCjr Software Downloads

As much as I hate to do this, here is the standard disclaimer:
  • I am providing these downloads as a convenience.  Use at your own risk.  I am not responsible for anything (good or bad) that happens.
  • If you are the author or copyright holder of a file appearing on this page, please let me know so that I can give you proper credit.  If you do not want your file to appear here, please let me know.
And now onto business ...

This page has some useful downloads.  Some of this software may work on a PC as well.  If you know of other PCjr software that belongs here, let me know.  I am not going to run a DOS shareware site or an abandonware site - if you need other programs to use on your PCjr, you are on your own.  No commercial software or copyrighted software (where the owner objects) will appear here.
