I've inherited some mid-90's era survey data in CavePlot format; it doesn't have a file extension, but a hexdump shows the string "Survey Data for CavePlot 2.0".
Unfortunately, it appears that the CavePlot homepage has fallen off the Internet [Edit: CavePlot homepage cached on the Internet Archive], email to caverdave@aol.com fails, so I do not have a copy of CavePlot, I don't know anything about it, and I also don't have an old G3 Mac which I believe would be required to run it (though I do have a modern x86-based OS X 10.5 Mac).
I'm looking for suggestions on ways to convert this survey data into a "modern" format, preferably Compass, Walls, or Survex; or worst-case, a way to view and work with the data in its current format. Help!
