A multicomputer system was designed and built to provide a means of transferring data from analytical instruments to a PDP-15 (Digital Equipment Corp., Maynard, MA) minicomputer. A model 6800 microcomputer (Motorola, Inc., Phoenix, AZ) was designed to accept data from instruments with diverse data formats and data collection times on a time-sharing basis. Once in the computer memory, the data are sent via a modified serial communications port to a PDP-15 minicomputer. The analytical instruments include an infrared spectrometer, two pulse height analyzers, an atomic absorption spectrophotometer, and a desk-top computer. This paper describes the versatility of the system, the microcomputer handling of the instrument I/O requirements, the changes in the PDP-15 to accept data at a 2400 baud rate, and changes in the TTY handler in the monitor to accommodate binary data and nonstandard byte configurations.
