The investigation reported here tested the use of a computer to assist in an ongoing archaeological excavation and survey. To provide rapid computer results, a remote terminal at the site was connected by telephone service to a time-sharing computer some 300 miles distant. Techniques developed and evaluated ranged from initial program preparation and testing through evaluation of field procedures in an environment involving an interactive computer. The ability to generate requested information rapidly enough to aid in tactical decisions affecting field procedures on a daily basis was demonstrated.
