As for simh I did keep binaries on the old sourceforge page ( https://sourceforge.net/projects/simh/ ) although it's not the aggressive new one on github. I know people cry about sourceforge but they went under new management years ago and fired everyone responsible for that piggyback fiasco.
Also in case anyone else is new to simh, you put the files in question in a folder then run path/to/pdp11.exe wherever simh installed it. CTRL+E is how you suspend the VM and can give it further commands from a simh> prompt, then the 'c' command to continue. Once inside the pdp11 vm "DIR" to confirm the stuff you're copying actually exists.
I've actually never gotten anything like this running before, very cool.
