Abstract
A general-purpose laboratory computer system using two Digital Equipment Corporation LSI-11 s in a master-slave relationship is described. The implementation includes hardware to install an LSI-11 as a slave parallel processor, to provide special-purpose functions such as a real-time clock and a 4K FIFO interprocessor buffer, and to establish a bus that permits the use of inexpensive interfaces to experimental equipment. The slave processor generates a complete log of each input or output event. Data in the form of the time of each event are continuously passed through the FIFO to a foreground task in the main LSI-11, which in turn stores the raw data on a hard disk. A macro library allows the easy development of experimentcontrol programs. A library of FORTRAN routines provides a pointer-based conditional and iterative search facility that can sift out any specifiable event or set of events from the data records for subsequent analysis. This computer system provides the user with an inexpensive facility to run up to 32 simultaneous experiments with complete data logging in foreground while program development, analysis, and word processing are concurrently being done in background.
