Numerical identification of microorganisms using the HP-41C calculator.

A program is described, which implements the algorithm of numerical identification of bacteria based on Bayes' theorem. The hand-held calculator HP-41C enables one to handle identification matrices containing more than 600 elements, which are packed in groups of five into one storage register. A part of the available storage is reserved for alpha-numeric designation of tests and species. Databases for different bacterial groups are stored on magnetic cards. Computation time does not exceed 400 s.
