- On a RISC OS 3 computer (particularly one with a 15 pin D type connector
- for the monitor) you should switch on the monitor before the computer.
- RISC OS 3 has the ability to automatically determine the type of monitor
- attached by means of identity signals from the monitor. In some cases,
- these signals will only be present while the monitor is switched on,
- hence the monitor should be switched on first.

- If you are using the PC Emulator on the A4 you might find that the \ key
- does not work. This happens because the A4 has a UK style PC keyboard
- layout. Add ‘KEYB UK’ to your AUTOEXEC.BAT file to load the UK keyboard
- driver.

- On computers before the A5000 it was only possible to use a 5.25inch
- floppy drive by adding a third-party disc buffer interface (because the
- 1772 Floppy Disc Controller does not generate enough current to drive
- all kinds of 5.25inch drive). Computers from the A5000 on use the 82C710
- or 82C711 as their Floppy Disc Controller. This device can drive a
- 5.25inch drive directly, so a disc buffer interface is NOT needed. For
- more information about attaching additional floppy drives to the A5000
- write to Acorn Customer Services, Acorn House, Vision Park, Histon,
- Cambridge, CB4 4ZT and request the ‘Support Group Application Note -
- Adding External Floppy Disc Drives to the A5000’.

- Typing special characters
- You can type the special characters shown in the keyboard map using the
- actions shown in the inset. For example, to type an upside-down exclamation
- mark (¡):
-
- 1Whilst holding down the Shift and Alt keys, press and release the '1'
- key ('¡' appears).
- 2Release the Shift and Alt keys.
-
- Typing accented characters
- Some of the keys on the figure below are marked with a black area in one
- corner. These keys allow you to accent characters. The accent in each case
- is the character nearest the black area of the key. For example, to type
- an 'e' with an acute accent (é):
-
- 1Whilst holding down the Alt key, press and release the '[' key
- (nothing seems to happen).
- 2Release the Alt key.
- 3Press and release the 'e' key ('é' appears).
-
- If you try to give a character an accent that it cannot have (eg. a 'g'
- with a cedilla) then the un-accented character will appear in step 3. To
- get an accent as a character on it's own, press the space bar in step 3.The
- RISC OS 3.10 upgrade contains an enhanced keyboard driver that makes many
- more characters readily available, such as accented characters, or symbols
- like ©. You can get at these extra characters using the Alt key. The
- keyboard map below shows all the characters that are available. Here's how
- to type them:
