4AM is a prolific computer historian whose practice involves cracking the copy protection on neglected Apple ][+ floppy disks, producing not just games, but voluminous logs that reveal the secret history of the cat-and-mouse between crackers and publishers.
4AM's logfile for their crack of the 1982 crack of Burger Time (which I played until my fingers bled, but on a Colecovision, I think) reveals some incredible, subtle trickery that played out within the extremely confined headroom of a 5.25" floppy's limited sectors.

The first two series of the comic are collected in Big Hard Sex Criminals, a fabulous hardcover whose plain pink wrapper comes off to make it look like you’re reading a book on DIY pet euthanasia.
