I have no suggestions on the processed data, but it might be worth an 
inquiry to the Trimble office in Westminster, CO to see if someone is 
willing to try extracting the data off those floppies.

Obviously the maps and processed information is probably more valuable 
at this point, but having the raw data accessible would be nice to a 
researcher too, and the guys in Westminster might take it as a challenge.
