Note: I am aware that the Teleport Modem is not made by Apple, but since it was 
packaged with all Performas I figured it appropriate to include.
 
Apple Fax Modem
Turn on the modem while holding down the button on the front panel. The modem will beep three times. Once it has beeped twice in sequence, press the button three times in rhythm with the next three beeps. If your timing is right, you will hear the modem speak digitally recorded voices of three developers saying their names. (Nice!)
FaxMaker for Teleport Modems
Choose "About FaxMaker..." from the Apple menu. Now click the icon in the window. The arrow pointer will change into a mouse, and a scrolling list of the developers appears.
 
Fax Terminal
Fax Terminal is an application that comes with the Geoport and Express Modem and is included in the Telecom package. When going to “About Fax Terminal...” drag your mouse over the icon of the fax machine. You will notice your cursor has changed to a question mark. Click on the icon and you will see some credits. Holding down command will speed up the credit list.
Ô£øGlobal Fax

•In version the German version 2.5.5, in the STR# resource of the extension, ID -8172, you will notice two error strings with a personal touch. This is how it appears in German, translated in English.
String 2 = Ein unbekannter Faxfehler ist aufgetreten. Pech!
[An unknown Fax error has occured. Bad luck!]
String 3 = Ein nicht unterstu:tzter Fax-Bilderstellungsvorgang wurde versucht. Irgendein Programmierer hat Mist gebaut!
[A not supported Fax picture build operation was attempted. A/some programmer bungled it (?)]
• Open the extension, version 2.5.6, with ResEdit and navigate to -8152 in the PICT picker there is a picture of a two-headed clarus the dogcow.

Teleport (In old versions the name was known as "Teleport Serial")
In the Teleport Serial Control Panel hold down Shift and click on “About...”. For those of you who don’t have the modem it says “Couldn’t find the modem”. The button you push to clear the message says “But I SEE One!”. This works in versions around 2.1 (not 2.5).
In version 2.5 open the Teleport Control Panel with ResEdit and go to the STR# Resource, open ID -4048, and scroll down to string 33. It will say, "Your TelePort is on fire. Please call the local fire department."
From: Bryan Cowan (moo@value.net)
In a newer version (possibly 2.5.5), if you open the TelePort Control Panel and Option-click the "Select Port" button, you can choose what modem picture you want displayed! You can choose from all the TelePort modems out. From: Norma Kirkham (NKirkham@epsb.edmonton.ab.ca)
Monitors: 
AV Monitor Software
From: Eric S. Wilson (FreefallML)
Some Code Names: Hammerhead (1705) and Sousa (1710AV)
In the Apple 1710 Monitor Software, AudioVision 14, and other AV packages, hold down Option while going to the about box. The normal about box changes from a picture of the monitor to a hammerhead shark holding a tuba with a musical note coming out.
Printers:
 
Personal LaserWriter SC
Personal LaserWriter SC Code Name: Shout
While running the Personal LaserWriter SC, version 7.0.1 (most likely other versions), click on the version number in the Page Setup or Print menu to see a list of credits.
 
LaserWriter 3000
While running the Personal LaserWriter SC, version 7.1 (most likely other versions), Option-click on the version number in the Page Setup or Print menu to see a list of credits.
The above two eggs also apply to a vast number of other drivers which will do the same thing.
Ô£øLaserWriter Egg
Pretty near impossible to do, but:
1) Power up with the rotary switch on the controller on "0".
2) Rotate the switch to "4", wait 3 seconds, then rotate the switch continuously for 10 seconds.
3) Stop on switch setting "5".
4) After about 1-2 seconds, the green light will start blinking and a
credits page will come out. (If you miss the timing, you have to power up again -- it only works on the first switch setting change!)
Some notes about what you will see: "Fast fish in a hot car" was the caption to a project T-shirt featuring an illustration from "One Fish, Two Fish, Red Fish, Blue Fish" (the printer's operating system was code-named Dr. Seuss). The "fast fish" is Bass, the *real* code name for TrueType. "Bass" itself is a play on "scaleable" fonts.
Guaranteed in revision 1.0, unknown in later revisions.
StyleWriter II Testing and Maze Egg (possibly other StyleWriters)
From: Dieder Bylsma (bylsma@unixg.ubc.ca)
This egg is hard to achieve but will work with some practice. If done properly, you will ultimately have a maze printed out by your printer. If you don't want to try any of the diagnostic tests and would like to see just the maze, instead of letting go at a desired flash, keep holding down the power button until it begins to print.
Instructions:
1. Unplug the Stylewriter II.
2. Hold down the Stylewriter II's powerbutton while plugging it back into the outlet, and keep holding the button down for 15 seconds. There will be no light or any indication that the SWII is powered up.
3. Release the power button, and then hold down the button again. Let go once the Paper-jam light (orange) has reached a desired number of flashes for the diagnostic test you want–the tests are below. (It has been found that the number of flashes is, in some way, directly related to how long you hold down the power button before and after plug-in.)
4. It will then start a diagnostic. Only way to abort the self-test is to
push the power-button on the Stylewriter II and turn it off. 
Diagnostic tests for each number of flashes:
1 - horizontal and vertical alignment pattern, along with 50%
and 100% black pattern and nozzle-pattern at bottom (nozzle-
pattern = diagonal swash that appears on the standard test page)
2 - single hairline across top of page with vertical drop on either side.
3 - dotted hairline test, and 50% and 100% black test bands made
unidirectionally
4 - 50% gray test whole page except for white rectangle in centre
5 - single hairline at the top of the page, three black 1/2 " x 1/4"
swatches underneath hairline. Same swatches reproduced in middle of page w/o hairline
6 - single hairline at top of page with black swatch underneath it.
7 - various horizontal test patterns on top 1/4 of page at various speeds,
i.e. draft, high quality etc.
8 and up - Prints a maze
Note: There are also on occasion the carriage return tests where the printer just cycles back and forth.
 
StyleWriter I
While running the StyleWriter I Printer Driver, version 7.2.3 (most likely other versions), click on the version number in the Page Setup or Print Menu to see a list of credits.
 
StyleWriter II
While running the StyleWriter II Printer Driver, version 1.2 (most likely other versions, but not version 1.0), Option-click the version number in the Page Setup or Print menu to see some more credits.
Note: The above eggs also work with other drivers.
 
Any StyleWriter
Release and then hold down the power button until the printer starts to print. This is a way to check the printing quality, but you will also see a picture of your printer, and maybe a company credit depending on the machine.
Other Hardware:
 
Apple CD 300 Plus
When your computer is starting up, hold down the keys c-d. It will show a list of credits from the CD-ROM driver and at the bottom is a button saying "huzza!" which, once pushed, will continue your start-up process.
AppleLink CD
Select "About AppleLinkCD" and hold down the Option key. The spinning CD turns into a spinning cat's head.
