While working on a small audio project, I dicovered this Easter egg on a microphone preamp board out of an old Mac. Printed on the back of the board is “© Apple Computer” — text you’d expect to find on any piece of Apple hardware of that date. However, you’ll notice that the letter L in Apple is the ichthys symbol colloquially referred to as the “Jesus fish”, and can be seen on vehicles nearly everywhere in the country. The sybolism has been around, on car bumpers at least, since the 1980s (credit to my girlfriend for finding out this fact). So, it’s entirely possible that someone slipped this into the circuit silkscreen before the boards went into production. I wonder what the real story is…
