ANSEC: A BASIC package for lag sequential analysis of observational data

Three BASIC programs for processing observational, nonconcurrent sequential data are presented. The programs follow Sackett’s lag sequential analysis method and have the innovations of running on interactional microcomputers and of providing plots of results. The outcome of the analysis is stored on a magnetic disk, facilitating a further application of probabilistic models to the transformed data. The Allison-Liker correction for the comparison test between expected and observed lag probabilities is included in the programs.     

A multipurpose laboratory package for 0S/8 BASIC

A set of BASIC-callable assembler routines are described that support experimental programming on the PDP-8/e laboratory computer. The package includes both general-purpose laboratory utilities (e.g., for timing delays, sensing and controlling switches, etc.) and specialized functions to facilitate elementary signal processing operations. System performance is evaluated in terms of timing accuracy, optimal sampling rates, and transportability to other laboratories.
