5. The left hand socket is used exclusively for the Operating System and will
already contain a ROM which must not be moved. The other four sockets are
for the paged ROMs.
6. The AMX ROM MUST be placed in a high priority socket, (i:e: one to the right)
and preferably number 15 (the furthest right). If a ROM expansion board is
fitted then socket 15 may be reserved for special use, if so then place the AMX
ROM in the highest priority socket possible, but anyway in one of the sockets
12, 13, 14, or 15. Installing the AMX ROM in a lower priority socket will slow
down the response of the mouse.
7. The pins on the ROM may require gently bending inwards to align them with
the socket:
8. Insert the ROM into the socket ENSURING THAT THE NOTCH IS AWAY
FROM THE KEYBOARD.
9. Check that all pins are correctly inserted and none are bent underneath.
10. Replace the keyboard and lid.
11. On switching on the message 'AMX Mouse off' should appear underneath "
BBC Computer". This message will not appear if the AMX ROM is placed in a
lower priority socket to any DFS or NFS (if fitted), although the ROM will still
function correctly.
The Mouse simply plugs into the User Port of the BBC. BEFORE CONNECTING
THE MOUSE UNPLUG THE COMPUTER FROM THE MAINS. The cable is then
connected to the socket on the underside of the computer as indicated in fig.2. Care must
be taken to ensure that the cable is inserted the correct way round: To do this pin 1 on the
computer socket, as indicated by the triangle, must match pin 1 on the plug, also indicated
by a triangle, and the locating key fits uppermost into the slot on the port housing.
