    Area of Science:

    • Behavioral neuroscience
    • Computer science applications in research

    Background:

    • Operant conditioning research requires precise control and data recording.
    • Existing systems may be expensive or lack flexibility.

    Purpose of the Study:

    • To describe a novel, affordable computer-based system for operant chamber control.
    • To detail the hardware and software components of the described system.

    Main Methods:

    • Utilized a TRS-80 microprocessor with 32K RAM and a floppy disk drive.
    • Implemented an LVB optical interface for up to 128 I/O operations across 8 boxes.
    • Developed the Operant Protocol System (OPS) using assembly language for real-time control and BASIC for user interaction.

    Main Results:

    • The system enables simultaneous real-time control and event recording for up to 8 operant boxes.
    • The LVB interface supports extensive input/output operations.
    • The system integrates dependable hardware with well-documented software.

    Conclusions:

    • The TRS-80-based system offers a reliable and inexpensive solution for operant conditioning research.
    • The system's design facilitates flexible experimental protocols, including variable schedules.
