The Computer History Simulation Project

The Computer History Simulation Project is a loose Internet-based collective of people interested in restoring historically significant computer hardware and software systems by simulation. The goal of the project is to create highly portable system simulators and to publish them as freeware on the Internet, with freely available copies of significant or representative software.


SIMH is a highly portable, multi-system simulator.

SIMH implements simulators for:

Also available is a collection of tools for manipulating simulator file formats and for cross-assembling code for the PDP-1, PDP-7, PDP-8, and PDP-11.
