On Tuesday, software engineer Doug Brown published his discovery of how to trigger a long-known but previously inaccessible Easter egg in the Power Mac G3’s ROM: a hidden photo of the development team that nobody could figure out how to display for 27 years. While Pierre Dandumont first documented the JPEG image itself in 2014, the method to view it on the computer remained a mystery until Brown’s reverse engineering work revealed that users must format a RAM disk with the text “secret ROM image.”
Brown stumbled upon the image while using a hex editor tool called Hex Fiend with Eric Harmon’s Mac ROM template to explore the resources stored in the beige Power Mac G3’s ROM. The ROM appeared in desktop, minitower, and all-in-one G3 models from 1997 through 1999.
“While I was browsing through the ROM, two things caught my eye,” Brown wrote. He found both the HPOE resource containing the JPEG image of team members and a suspicious set of Pascal strings in the PowerPC-native SCSI Manager 4.3 code that included “.Edisk,” “secret ROM image,” and “The Team.”
