Screenshots?

Also, it's hard to understand "what" this is emulating. Does it start and boot up? Do I need to find the OS somewhere? Can I run any IBM 1130 program, or do I need to provide some other kind of virtual something? How would I actually go about running a program written for the IBM 1130?

It seems to be a link to a development branch. The authors may not have intended this to be shared in its current state.

The IBM 1130 doesn't have a screen.

Is it all vibe coded? Looks and feels like LLM slop.
