SIMH is a highly portable, multi-system emulator which runs on Windows, Linux, Mac OS X, FreeBSD, OpenBSD, NetBSD and OpenVMS. It is maintained by Bob Supnik, a former DEC engineer and DEC vice president, and has been in development in one form or another since the 1960s.

History

SIMH was based on a much older systems emulator called MIMIC, which was written in the late 1960s at Applied Data Research.^[1] SIMH was started in 1993 with the purpose of preserving minicomputer hardware and software which was fading into obscurity.^[1]
