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?

First computer I used was an ibm 1130. punched cards and green-bar line printer paper. I remember it didn't have much memory, so I had to read/write data to a (giant sized, small capacity) hard disk. All Fortran.

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