Custom VT100 OS Simulation

I've created this custom OS simulation for an alternative reality game I'm imagining. I tried to stay as true to the original DEC VT100 terminal as possible with the art and the capabilities, which is why I'm not super happy with the font that doesn't match the system. I should also mention that as far as I was able to determine the VT100 might not have had any way to use an OS, so this might as well be considered a VT180, though because they had the same design other than the display color, it doesn't really matter. The OS actually gets all the data from a server, almost like a terminal, which was necessary since otherwise the users can easily decode the whole game.
