7.9.5.2 SIMH
SIMH is an emulator for old computer systems, and is part of the Computer
History Simulation Project [

] (note here simulation is used to refer to instruction
emulation rather that true hardware simulation).
SIMH implements instruction emulators for:

One of the most important systems it emulates is VAX, and it can run OpenVMS
operating system. The Computer History Simulation Project also collects old
