Commodore 64

"Commodore 64" was the nickname given by Charlie Bradbury to the computer warning system of the Men of Letters.

Description
This old and massive computer unit was located inside the Men of Letters bunker. According to Charlie, it has  encryption software and appeared to be powered by something magical. Charlie said that the whole system acts like an alarm in cases of global catastrophe, such as angels being cast out of Heaven, as Kevin Tran has witnessed. Charlie added that during circumstances like those, the system shuts down the bunker.

Sam asked Charlie if they could use the system to track angels, to which Charlie replied she would see what she could do. After some tinkering, Charlie claimed that they could now download files into the system, and then proceeded to import all the files of the Men of Letters.
