- EXAMINE memory commands will now produce minimal output that summarizes multiple successive locations with the same contents and may be aborted by SIGINT (Control-C).
- Ethernet enhancements on all platforms and and much simplified platform support on macOS.
- Almost all existing simulators have useful SET CONSOLE SPEED=nnn behaviors in both the bare console session as well as TELNET console sessions.
- Simh global/startup configuration commands can be contained in the first of simh.ini found in: 1) The current working directory, 2) The User login directory, 3) The directory containing the simulator executable, 4) The ~/Library/Preferences directory, 5) The /Library/Preferences directory, or 6) The /etc directory.
#### All simulators build cleanly under OpenVMS on ia64 systems.
