Replacing BBC Master battery pack
=================================

Unplug and take out the old pack.  The new pack slots down in the gap next
to the keyboard.  The lead is plugged in so that the empty hole is towards
the keyboard.
                        +-+
     Battery -----------|O|
      Pack   -----------|O|    Keyboard |
                        |O|             |
                        +-+             V

Hold down the 'R' key, then turn on the computer.  It should say
'CMOS ram reset.  Press Break'

You will then have to reconfigure.  Some sensible options are:

*FX162,6,255                       Fast way to *INSERT
*FX162,7,255                        all the ROMs
*CONFIGURE LANG 12                 Comes up in Basic
*CONFIGURE FILE 9                  Comes up in DFS
*CONFIGURE MODE 7                  Comes up in MODE 7
*CONFIGURE PRINT 1                 Set to parallel printer

These are the minimum to have the machine working usefully.  You can also
set:

*CONFIGURE BAUD 7                  Serial speed set to 9600
*CONFIGURE DATA 4                  Serial data type (8 bits)
*CONFIGURE NOBOOT                  Don't boot disks on switch-on
*CONFIGURE DELAY 25                Pause before keys repeat
*CONFIGURE REPEAT 5                Key repeat speed
*CONFIGURE FDRIVE 0                Floppy drive speed
*CONFIGURE FLOPPY                  ADFS defaults to floppy drives
*CONFIGURE IGNORE                  Printer ignores nothing
or *CONFIGURE IGNORE 10            Printer ignores CHR$10, line feed
*CONFIGURE LOUD                    Loud speaker
or *CONFIGURE QUIET                Quiet speaker
*CONFIGURE FS 0.254                Network fileserver, default is 0.254
*CONFIGURE PS 0.235                Network printserver, default is 0.235

To set the time, you need to be in Basic:
*BASIC
TIME$="Wed,21 Oct 1992.12:30:00"   Change as appropriate, but you must have
          ^  ^   ^    ^  ^  ^      the comma, spaces, full stop and colons.
