I have not implemented and experimented with SIMH for a long time.

Nor have I done much diligent research in the meantime! smiley

I read somewhere that regardless of how quiet (even halted) the guest operating system in SIMH is, the CPU in the host OS is pretty much maxed out with the process running SIMH.

If that's the case and you wanted to run an emulated VMS 24X7, then cooling efficacy in the rig would have to be examined.

Thanks!

Bye, the bye, these tools could be of use with SIMH in the windows world:

SET CPU IDLE

I have three instances of VMS running right now and my load not much more than it would normally be (1.1).

No more VAX hobbyist licenses. Community licenses for Alpha/IA64/X86_64 VMS Software Inc. Commercial VMS software licenses for VAX available from HPE.

Just re-visiting.. No more hobbyist licenses? Is that from vmssoftware.com, no 'community' licenses?

I recall that the disks failed on the public access VMS systems that included Fafner

Anyone know what happened to FAFNER.DYNDS.ORG? I had a hobbyist account here but can longer access the site.

At one time, didn't this web site have a job board? I would love to use my legacy skills one last time in my career.

Eisner, which is currently being moved, got an SSH update and the keys were updated to more modern encryption standards.
