Computer History Simulation Project

SimH is an open-source project providing highly portable simulators for historically significant computer systems, including DEC PDP and VAX machines, IBM systems, Data General, HP, Honeywell, and others. Maintained primarily by Bob Supnik with contributions from others such as J. David Bryan, the site offers downloadable simulator source code, documentation, software kits, and papers on the history of computing and simulation. It represents a long-running individual/volunteer effort rather than an institutional archive.
