Thanks for posting this! I had a lot of fun exploring the similarities (and differences) of early Unix and the Unix-likes I’ve worked with under CLI, like Linux and NetBSD.

There is a typo in your “More photos on SIMH site” link. Should be http://simh.trailing-edge.com/photos.html .
Beyond that: awesome! I look forward to playing with this.
