Open VMS Hardware compatibility

Can Open VMS be installed on AMD or Intel machines or does it require VAX architecture?

It appears to run only on VAX, ALPHA and Itanium processors. There is something called Free VMS available at http://www.freevms.net that supposedly runs on i386 and AMD64 but I don't know anything about it except that it seems to not have gotten very far in development. You might also try http://www.forest-edge.net/evax.html which is a VAX emulator.

OpenVMS runs just fine on AMD and Intel processors; it's somewhat slower on x86-32 and x86-64 architectures than where running native, but it can and does boot and run just fine.

simh and the Stromasys packages are far more common choices than the Forest Edge software; the latter is about ten years old and not AFAIK actively maintained.
