SIMH
SIMH is a highly portable, multi-system emulator which runs on Windows, Linux, Mac OS X, FreeBSD, OpenBSD, NetBSD, OpenVMS, and other operating systems. It is maintained by Bob Supnik, a former DEC engineer and has been in development in one form or another since the 1960s.
History
The Origin of SIMH
SIMH was based on a much older systems emulator called MIMIC, which was written in the late 1960s at Applied Data Research. [1]
SIMH on the PC
SIMH was started in 1993 with the purpose of preserving minicomputer hardware and software which was fading into obscurity. [2]
