1.12) What 'Easter Eggs' are present in RISC OS?

It has been a long tradition with Acorn OSes to have hidden sections that give credit to the people involved in the creation of that OS. The BBC Model B ROMs had the names of the people involved hidden in the memory space occupied by Fred, Jim and Shelia. With the release of the ARM powered machines this tradition has continued on.

RISC OS 2.00

* tucked away in the ROMs is a list of the names of involved people.

RISC OS 3.00

* If you type 'rmtmd' when the desktop welcome screen is displayed a slide show of the key RISC OS team members is displayed on the screen.

* In the info box of the task manager if you clicked menu over the letters 'rmtmd', in that order, contained within the author icon a full list of the people involved with the OS's development is displayed in that icon.

RISC OS 3.10 & 3.11

* In the info box of the task manager if you clicked menu over the letters 'team', in that order, contained within the author icon a full list of the people involved with the OS's development is displayed in that icon.

* Using a template editor examine the task managers templates file from the Resources filing system. (Resources:$.Resources.Switcher.Templates)<li>Inside the 'power' dialogue is a message.

RISC OS 3.50

* In the info box of the task manager if you clicked menu over the author icon four times a full list of the people involved with the OS's development is displayed in that icon. (This can take a while to watch, be warned...)

* Using a template editor examine the task managers templates file from the Resources filing system. (Resources:$.Resources.Switcher.Template3D) Inside the 'power' dialogue is a message, in 3D. This message also appeared in the replacement templates supplied with NewLook for RISC OS 3.1.

RISC OS 3.60

* In the info box of the task manager if you clicked menu over the author icon four times a full list of the people involved with the OS's development is displayed in that icon. (This can take a while to watch, be warned...)

* Using a template editor examine the task managers templates file from the Resources filing system. (Resources:$.Resources.Switcher.Template3D) Inside the 'power' dialogue is a message, in 3D. This message also appeared in the replacement templates supplied with NewLook for RISC OS 3.1.

* Run the program listed in the RISC OS 3.50 section to be given a list, and pictures, of the primary developers of RISC OS 3.60.

RISC OS 3.70

* In the info box of the task manager if you clicked menu over the author icon four times a full list of the people involved with the OS's development is displayed in that icon, including a 'special' acknowledgment to Peter Bondar. (This can take a while to watch, be warned...) This only works if the menu was opened from the Task Manager window, not the icon.

* Using a template editor examine the task managers templates file from the Resources filing system. (Resources:$.Resources.Switcher.Template3D) Inside the 'power' dialogue is a message, in 3D. This message also appeared in the replacement templates supplied with NewLook for RISC OS 3.1.

* Run the program listed in the RISC OS 3.50 section to be given a list, and pictures, of the primary developers of RISC OS 3.70.

RISC OS 3.71

* In the info box of the task manager if you clicked menu over the author icon four times a full list of the people involved with the OS's development is displayed in that icon, including a 'special' acknowledgment to Peter Bondar. (This can take a while to watch, be warned...) This only works if the menu was opened from the Task Manager window, not the icon.

RISC OS 4.02

* From BASIC, issue the command SYS "OS_Module",2,"IRQUtils" and RISC OS will launch an invaders game.

* Click MENU over the RISC OS 4 icon on the far right of the iconbar. Move the pointer over to 'Info' and then across to open the RISC OS 4 information box. Click MENU four times over the icon containg ' 1999, RISCOS Ltd'. Sit back and watch a list of RISCOS Ltd. developers scroll by.

* Using a template editor examine the switcher module's file in the Resources filing system. (Resources:$.Resources.Switcher.Templates) Inside the 'power' dialogue is the message "Help! We've been released from the software factory, and don't know what to do!". There is another one inside the 'Confirm' template. :-)
