The Computer History Simulation Project 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. Simulators SIMH is a highly portable, multi-system simulator. ● Download the latest sources for SIMH (V3.5-1 updated 15-Oct-2005 - 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. 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 here. 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 ● IBM 1401, 1620, 1130, System 3 ● Interdata (Perkin-Elmer) 16b and 32b systems ● Hewlett-Packard 2116, 2100, 21MX ● Honeywell H316/H516 ● 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.
