We recently lost the jump-project.org web site, and all of the resources that were available from that site. I was worried the same thing might happen with the JUMP web site hosted by Vivid Solutions. So I grabbed the source code and executable distributions for JUMP from that web site and put them on my SurveyOS SourceForge project page. I also put a zip file with all the PDF documents from the original JUMP there. I also put a maker web page for these resources on my Redefined Horizons web site.

This may be useful for programmers interested in the original JUMP source code.
