SE Easter Egg
I’ve been meaning to try this one out for years. I just keep forgetting about it. It seems there was enough space left over in the SE’s ROM to add 4 images of the developer team. In order to display them, you have to type “G 41D89A” into the debugger.
If you have a programmers’ switch, you can press the interrupt button to bring up a debugger.
If you don’t have the switch, you can always reach into the grill with something and push the button on the side of the analog board. However, every time I’ve pressed the switch in the past, the Finder has just restarted. I’ve never been given a debug window. I think you really have to have something (i.e. the Finder) crash on you for it to work.
Luckily, I had the Finder lock up on me when I was trying to read a Zip disk that just gave up the ghost. Remembering the trick, I pressed the interrupt switch and crossed my fingers. I was finally given a debug window.
I typed “G 41D89A” into the debugger and pressed Return. The 4 images immediately began to display one after another as a slideshow.
Another Easter Egg that’s not documented a whole lot, and less known, is the “Stolen From Apple Computer” image that Apple put in the ROM. Back in the day, there were more than a handful of companies cloning the Apple II. Some went as far as to outright copy the Apple II ROM byte-for-byte. Apple wanted to put something in the Macintosh ROM that would unequivocally prove in a court case that the offender stole the ROM. They hid a “Stolen From Apple Computer” image in the ROM that could be displayed by typing “G 4188a4” in the debugger.
It’s nothing glamorous, but here it is:
Amazing how they went to such a great length to protect the Macintosh. I guess it worked. I don’t recall anyone cloning it.
