Typically you need to have devices online so the OS will see them at startup. But for removable media devices (tapes and many disks) you may want to mount the media (image files) later on, and switch them at runtime, exactly as you would do with disk packs or tape reels on a real computer.

Yes, but you were not able to attach in your startup script? That's when to do it. Bill Degnan twitter: billdeg vintagecomputer.net On Dec 31, 2017 3:59 PM, "Mark J. Blair via cctalk" wrote: > I've been experimenting with the SIMH VAX simulators a lot lately. The > only

Attaching SIMH devices without halting simulation?

I've been experimenting with the SIMH VAX simulators a lot lately. The only way I know of to mount a tape, disk pack, CD-ROM, etc. after boot time is to halt the simulation with ^e to get to the SIMH command prompt, ATTACH the desired image, and then resume the simulation with CONTINUE. Is
