Averager System for the Classic Linc

This document details the Averager System, a set of programs developed by the Biomedical Computing Division at the University of Wisconsin Medical Center for the LINC computer. The system is designed to compute the average response of signal-generating devices to a series of excitations (such as human evoked cortical responses) and can also generate latency histograms for zero-or-one devices like discriminated neural firing.

The system is comprised of three primary programs:

• AVERAGER: The core program that provides functions for simultaneous one-input or two-input averaging, latency histogram generation, filing of averaged data to tape, and plotting of data on a CalComp plotter or the LINC oscilloscope.
• LATAMP (Latency and Amplitude Measurement): A utility program intended for use with data produced by the AVERAGER program, allowing users to retrieve, display, and measure the latency and amplitude of specific points on a waveform using a cursor.
• AVELIST (List Average Data): A utility that generates a list of blocks containing data produced by the AVERAGER program, printing the data identification along with each block number.

The document includes detailed operational procedures, technical specifications, information on memory usage, hardware configuration requirements, and the data tape format used by the programs.
