- When using word processors with various dot matrix printers printers,
- customers often have problems with printing '£' signs. In the large majority
- of cases on both 8 bit and 32 bit based systems using the '#' within your
- word processor in place of the '£' will make the printer print the '£'
- symbol. Some word processors do however automatically convert the '£' symbol
- into a '#' before sending it to the printer. Please note that if you are a
- user in education, all LEA Advisor contacts have been sent a copy of the
- complete package and you can therefore contact them to be supplied with a
- copy of the BBC Model B Emulator for your school.

- Although the mice supplied with Archimedes and BBC A3000 have proven to be
- very reliable it is inevitable that they will eventually begin to wear
- out. The mouse is one of the very few mechanical parts of the system and is
- extremely heavily used. Acorn Approved Dealers are able to supply various
- spares for the mouse such as cables for both Digimouse and the Logitech
- mouse, and also spare balls and retaining clips for the Logitech mouse.
- Please note that in a lot of cases when people think their mouse has become
- faulty it does in fact only need cleaning. Full instructions on cleaning the
- mouse ball and the rollers can be found in either the User Guide or Welcome
- Guide supplied with the computer.

- In both 300 series machine (fitted with an Acorn backplane), old 440
- systems and all 400/1 series machines, the fan has a filter to extract dust
- from the air. This filter should really be replaced anually to ensure a
- smooth throughput of air. The spare fan filters can be purchased from your
- Acorn Approved dealer. Full instructions on replacing the filter can be
- found in either the User Guide or Welcome Guide supplied with the computer.

- Earlier versions of the PC Emulator ignored the floppy disc drive step rate
- values, which are stored in CMOS RAM, and controlled the FDC (Floppy Disc
- Controller) directly. On the BBC A3000 and Archimedes 400/1 series machines
- this resulted in excessive noise from the floppy disc drive when used with
- the PC Emulator.
-
- Version 1.33 of the PC Emulator provides a cure for this by reading the step
- rate values stored in the CMOS RAM. This change limits the PC Emulator to a
- total of 3 floppy drives, as opposed to the 4 which are supported in
- previous versions.
-
- The setting of the step rate for the second drive becomes very important
- when using a 5.25" drive with the PC Emulator. You can experiment with the
- step rate values as illustrated with the example below.
-
- *Configure Step 12 1
-
- This will set the step rate of the drive to the slowest value possible with
- the 1772 disc controller, other possible values are 6, 3, 2. An explanation
- of this command can be found in the User Guide supplied with the machine.
