Evolution of Author's Use of Early 3D Recording Technologies - 1979 to 2007
Richard Clymer with first HP Computer Transit in North American archaeology- First deployed in the at Raritan Landing  by Dr. Grossman in 1979.  It was limited to angle distance measurements, had no memory, and all readings had to be hand-entered into a seperate module.
Second generation of computer Transit deployed by Dr. Grossman at the Broad St. four years after Raritan Landing - Note attached portable computer programmed to serve as a data collector and calculator to convert raw angle and distance readings into  coordinates with the in-house programs written in Basic.
