PC Card devices

6.2 Keyboard
When installing DOS or Windows you will probably have to specify the keyboard that you are using. This varies depending which Acorn Computer your PC Card is installed in. 
 
  • If the host machine is a Risc PC then the keyboard should be configured as UK/English. 

    •  
  • If the host machine is any of the older Acorn computers (A5000, A3000, A400, A300) then the keyboard should be configured as a United States keyboard.

    •  
  • If you have a foreign keyboard on any host machine (eg German), then you should indicate it when installing software.

6.3 Mouse
The host computer’s mouse is emulated for the PC Card as a Bus Mouse. Installation software will usually set this up for you. 

To use the mouse under DOS you need a mouse driver suitable for bus mice. A modern version of DOS will install a suitable one for you, usually called MOUSE.COM. 

Note that if you have previously used the Acorn PC Emulator/PC Soft then you must remove all copies of the AMOUSE.COM supplied with that as it is incompatible with Aleph One PC cards.

Aleph One mouse driver

Only if you wish to save memory, or if you do not have a mouse driver supplied with your version of DOS, is there any need to use the supplied Aleph One mouse driver (AMOUSE.COM). This is a simple driver with minimal functionality so it takes up very little DOS memory. To install this: 
 
  1. Copy AMOUSE/COM from the Drivers/Mouse directory on the !PC software floppy to your DOS partition (see Moving files between RISC OS and DOS on page 34). 
  2. Invoke the driver by typing AMOUSE at the DOS prompt. 
  3. Normally you would want to add the AMOUSE command to your AUTOEXEC.BAT file so that it is always executed on startup.

Using the mouse with Windows

To use the mouse under Windows you need do nothing more than accept the defaults when installing Windows. 

 Using the mouse in multi-tasking mode

When running in multi-tasking mode, you will see up to two mouse pointers on your computer screen: the RISC OS pointer and the PC pointer (either DOS or Windows, depending on the software you are running). 
The mouse can only drive one pointer at a time, so you should choose Connect mouse from the PC card menu inside the PC card window. This will allow the PC pointer to be used. 

To reconnect the RISC OS pointer, click Menu. 

When the mouse is connected to the PC pointer, you will not be able to switch from multi-tasking to single-tasking mode by double-clicking: reconnect the mouse to the RISC OS pointer first by clicking Menu.
