Open SimH (History Simulator) is a collection of simulators for
historically significant or just plain interesting computer hardware
and software from the past.
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.

Open SIMH provides a large (and growing) number of simulators:

This package contains the Open Simh version, the 4.X stream,
which can be found in github.
Open SimH is more advanced and implements more simulators than
the "classic" SimH, but is also CI/CD work.

Note: Please add /opt/open-simh/bin to your $PATH or simply
      invoke each simulator with open-simh-"name".
      Example: open-simh-vax
