CD ROM Eggs 
7200 System Software CD QuickTime Video
7200 Code Name: Catalyst  From:
Mukesh Agrawal (quichem@umich.edu)
In the System 7.5.2 Software CD, Version 1.0, for the 7200/75 and 7200/90 (the CD that you use to reinstall the system software), there is a QuickTime movie of the 7200 testing team in Ireland. It is an invisible file called "7200 QCRM Movie".  The path is Apple Extras/QuickTime Extras/Movies /Photos/7200 QCRM Movie.  

Since it is invisible, you need to copy the Photos folder to your hard drive, and then used ResEdit to make the file,"7200 QCRM Movie", visible by Getting Info. on it; or you can open MoviePlayer or SimplePlayer first and then open the file from the application.

Random Number
From: Matt Brubeck (mbrubeck@jetbbs.com)
In the Performa CD that comes with Performa 6100's and has system 7.5 on it, the file in the Restore All Software folder, called Data File 46, is actually a folder.  It is the system folder used by the Performa CD.  It contains, along with the system software and an invisible System, a folder with a blank icon titled with something that looks like a phone number, 694-0330.  Does anyone know what  this number means?  I tried it in the Cupertino area code but the number did not exist.  It is a bit peculiar.  

System 7.1 AV CD-ROM
Code Names: Quadra 660AV was Tempest and Quadra 840AV was Quadra 1000 and Cyclone
There is an invisible QuickTime movie, “Our Gang!”, inside the Preferences Folder, inside the System Folder in the disk “Macintosh CD-Install Me First” that came with my 840AV and the 660AV; and has system 7.1 in it.  It may also come with other computers but I am not sure.  The CD has a 5 minute home made video by one of the programmers at Apple. 

Since it is invisible, you need to copy the Preferences folder to your hard drive, and then used ResEdit to make the file,"Our Gang!", visible by Getting Info. on it.  Or you can open MoviePlayer or SimplePlayer first and then open the file from the application.  There are also a couple of pictures of the development team tucked away in the ROM of the CD.

Parade
The coolest one, by far, was the parade hidden on the CD containing 
version 7.0a9. All I can offer are some still shots from the storyboard... It worked something like this: an alert came up when you booted the software. This alert had a bunch of legalese about no warranty and pre-release software, and you had to dismiss it to continue the booting process. But if you left the alert alone for ten minutes, then the parade would start. It began by having an animated band leader push the text of the alert out of the way. Then a curtain would come down behind him as the music started to play (a 1954 recording of Kid Ory's Creole Good Time Jazz Band performing When the Saints Go Marching In). Across the screen marched an assortment of circus performers carrying a banner. The banner had a lot of text about the people on the project. Sheila Brady was the main artist on the parade.  This picture is shown at 50% of the actual size....

Not A Parade
Version 7.0a12 also went out on a CD, and we didn't take the time to make something as cool as the parade. I just couldn't bear to put nothing at all in its place, though. One of the things developers would do is use MacsBug to defeat the 10 minute time delay on the a9 parade. I thought this was cheating, so I made it extra hard (i.e impossible) to defeat the time delay on the secret boot-time Easter Egg in 7.0a12. After 7 minutes of waiting (I thought 7 minutes was far more appropriate than 10 minutes...) a still shot came on the screen. No music, no animation. It was really lame compared to the parade, but I thought it was way better than nothing. Sheila Brady was the main artist on the non-parade.  This picture is shown at 50% of the actual size....
