I can't even run a binary from one Linux distro to the other, let alone one from a random Unix from the 80s. If a rebuild from source is allowed (which would need to allow modifications to the build system) that's a completely different game.

As an unmodified binary from the 1980s on current Linux/Unix? Highly unlikely.

Just used xev today (bought new mouse few days ago and it wasn't responding in chrome so I wanted to be sure).
