I have been running VMS lately, and I have compiled a list of emulators.
Simh: works flawlessly, networking works perfect. It is cross-platform.
ES40 (AlphaSim): very slow, VMS crashes when DECnet starts. Other than that, it emulates the whole system including the SRM firmware, where other emulators only provide the "boot" command and a few others. It is cross-platform, but networking works on Linux.
AlphaVM-Free: hard to find today, but works the best. Fastest emulator available for free, and supports the most RAM. There is a Linux version, but I can't find an installer for it.
FreeAXP / vtAlpha: emulates an AlphaServer 400, so older VMS versions can run. Has RAM restrictions, but works well and is up-to-date. Windows only.
There seems to be a new emulator, called DECaxp: https://github.com/JonathanBelanger/DECaxp
It looked promising, but it now looks dead. Has anyone had any experience with Itanium emulation? I saw an emulator called Ski, but it only emulates CPU instructions.
Discussions about *nix and Other Operating Systems should go in this forum.
