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.
Download the latest sources
for SIMH (V3.8-0 updated 15-Jun-2008
- see change log).
Download a zip file containing Windows
executables for all the SIMH simulators. The VAX and PDP-11 are
compiled without Ethernet support. Versions with Ethernet support are
available here (requires that
WinPcap 4.0 be installed). If you download the executables, you should
download the source archive as well, as it contains the documentation and
other supporting files.

If your host system is Alpha/VMS, and you want Ethernet support, you need
to download the VMS Pcap library and execlet
SIMH implements simulators for:
Data General Nova, Eclipse
Digital Equipment Corporation PDP-1, PDP-4, PDP-7, PDP-8, PDP-9, PDP-10,
PDP-11, PDP-15, VAX
GRI Corporation GRI-909, GRI-99
IBM 1401, 1620, 1130, 7090/7094, System 3
Interdata (Perkin-Elmer) 16b and 32b systems
Hewlett-Packard 2114, 2115, 2116, 2100, 21MX, 1000
MITS Altair 8800, with both 8080 and Z80
Royal-Mcbee LGP-30, LGP-21
Scientific Data Systems SDS 940
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.
