Managed to capture some video of the BeMachine running the Hobbit-93080009.img available online. It's weird looking at this proto-BeOS, predating the PPC BeBox, and a lot of evolution of the system. Still many familiar icons and interfaces...

I'm still working on how to best capture video. This is VGA from the machine to VGA->HDMI adapter to an HDMI capture interface to OBS, cropping and scaling to get close to the 4:3 source image.
