About This Library

These programs are classic BASIC applications from the CP/M and early PC era (1970s-1980s). They demonstrate the creativity and programming skills of early computer enthusiasts who created powerful applications within the constraints of 1980s hardware.

Historical Sources

The programs in this library have been preserved from historical archives including: - Oakland Software Repository (OAK) - One of the largest CP/M software archives - Simtel - Historic software archive from the 1980s-1990s - CP/M CD-ROMs - Collection CD-ROMs from the CP/M era - Walnut Creek CD-ROM collections - Preserved software from the 1980s-1990s - Other historical archives and user group libraries

These programs represent the collaborative work of countless programmers, hobbyists, and enthusiasts from the early personal computing era. We preserve them here for educational and historical purposes. All programs are provided as-is from their original archived sources.
