The use of a microcomputer in a biomedical research project.
The use of an inexpensive microcomputer system in an NIH-supported biomedical research project is explained. Computer programs which store and analyze air pollution data; records from hospitals, doctors' offices, pharmacies, and schools; and data from a community public health survey are described.
