Bridged devices require macOS 10.15 to work correctly. Check if we're on macOS 10.15 at runtime (so a newer SDK can be used to make simh binaries that target older macOS), and at compile time (so an older SDK can be used to build simh). Also make it so vmnet: for host only is deprecated; you must explicitly provide either host, shared, or a bridged device name.
Open SIMH machine simulator
This is the codebase of SIMH, a framework and collection of computer system simulators.
SIMH was created by Bob Supnik, originally at Digital Equipment Corporation, and extended by contributions of many other people. It is now an open source project, licensed under an MIT open source license (see LICENSE.txt for the specific wording). The project gatekeepers are the members of the SIMH Steering Group. We welcome and encourage contributions from all. Contributions will be covered by the project license.
The Open SIMH code base was taken from a code base maintained by Mark Pizzolato as of 12 May 2022. From that point onward there is no connection between that source and the Open SIMH code base. A detailed listing of features as of that point may be found in SIMH-V4-status.
