Amiga hardware and software
Source: Raymond Chen
On the Amiga (NB), press and hold the following keys:
LeftShift, LeftAlt, RightShift, RightAlt
Now press one of the 10 function keys. (Keep those four keys down!)
Each function key produces a different message.
To get the rude message, insert a disk into the internal drive.
(Still holding down all those keys?) Now eject it.
"We built the Amiga..."
and when you pushed the floppy back in:
"...and Commodore f**ked it up!"
The rude message has been deleted from newer versions of KickStart.
Get 1.2/33.166 or earlier.
NeXT systems and software

In Improv (version 1.0) for NeXTstep from Lotus, go to the Info Panel, and in the space to the left of the Improv title, hold down shift, alternate, and command, and click the mouse. A "little man" with big bug-eyes shows up....
To clear it, you quit Improv.
From the debugger, enter "G 40E118".
This gives you a "Stolen from Apple Computer" message.
Hit the interrupt switch (the button with the broken circle on it, on
the left side of your machine closer to the back) to go into the
built-in debugger, and enter "G 41D89A".
Four bitmap pictures of the Macintosh development team appear as a slideshow. Reboot (hit the button closer to the front, with the triangle on it) to get out of the endless cycle.
Hold down Command-Option-x-o right after you turn on or reboot the machine.
The Classic starts up from a minimal ROM-disk which contains System 6.0.3, Finder 6.1x, and AppleShare. (This version of the System is not recommended to run the Classic under.) If you look at the ROM-disk with a program able to see invisible files (like ResEdit or MacTools), you'll find folders hidden there bearing the names of the Classic designers.
Set the system date to 9/20/89 (the release date of the IIci), and set your monitor to 8-bit color. Restart while holding Command-Option-c-i.
You'll see a color picture of the IIci design team. Click the mouse to continue.
Set the system date to 3/19/90 (the release date of the IIfx), and restart while holding down Command-Option-f-x.
You'll see a color picture of the IIfx design team. Click the mouse to continue.
