BASIC-11 Laboratory Extensions

This document, the BASIC-11 Laboratory Extensions User's Guide, provides comprehensive instructions for using software extensions to control various peripheral hardware on the PDP-11 system, including the LPS11, AR11, and DR11-K. The guide covers the necessary routines for data sampling, real-time clock control, digital input/output operations, and display management. Additionally, it contains detailed instructions on how to build and link the load modules required to incorporate these extensions into BASIC/RT-11, BASIC/CAPS-11, and BASIC/PTS-11 systems, along with error message summaries and glossary definitions.
