Important Information
Wiring the Mains Plug
WARNING: The ARM Evaluation System must be earthed.
The wires in the mains lead are coloured in accordance with the following code:
Green and yellow
Earth
Blue
Neutral
Brown
Live
As the colours of the wires may not correspond with the coloured markings
identifying the terminals in your plug, proceed as follows:
•
The wire which is coloured
green and yellow
must be connected to the
terminal in your plug which
is
marked by the letter E, or by the safety earth
symbol or which is identified by being coloured green, or green and yellow.
•
The wire which is coloured
blue
must be connected to the terminal which is
marked with the letter N, or coloured black.
•
The wire which is coloured
brown
must be connected to the terminal which is
marked with the letter L, or coloured red.
If the socket outlet available is not suitable for the plug supplied, the plug should be
cut off and the appropriate one fitted and wired as previously noted. The moulded
plug which was cut off should be disposed of as it would be a potential shock hazard
if it were to be plugged in with the cut off end of the mains cord exposed. The
moulded plug must be used with the fuse and fuse carrier firmly in place. The fuse
carrier is of the same basic colour (though not necessarily the same shade of that
colour) as the coloured insert in the base of the plug. Different manufacturers' plugs
and fuse carriers are not interchangeable. In the event of loss of the fuse carrier, the
moulded plug MUST NOT be used. Either replace the moulded plug with another
conventional plug (wired as previously described) or obtain a replacement fuse
carrier from an authorised Acorn dealer. In the event of the fuse blowing, it should
be replaced, after clearing any faults, with a 5 amp fuse that is ASIA approved to
BSI 1362.
Exposure
Like all electronic equipment, the ARM Evaluation System should not be exposed to
direct sunlight or moisture for long periods.

1. Introduction
The ARM microprocessor is mounted on an evaluation board which runs as
a co-processor to a BBC Model B or BBC Master Series microcomputer and
supporting peripherals.
This document defines the complete evaluation system, comprising either of
the computers mentioned above, the ARM co-processor, supporting disc
drives, monitor, interconnecting cables, ROMs and documentation.
It describes how to install and operate the system and provides a check-list
of the required component parts, discs and documentation.
An operational description of the co-processor is also given.
The discs included in the Evaluation system are Acorn ADFS format discs.
If your equipment is unable to read these discs you should purchase the
following two items from an authorised Acorn dealer.
Product Code Product name
ANB29
ADFS ROM kit
ANB28
1770 Upgrade kit
Clearly if your system already has a 1770 disc controller then only ANB29
will be required.

2. System components
An evaluation system should be made up of the ARM Evaluation system
itself plus a number of other components. A complete system should be
made up of the following elements:
(1)
A BBC Model B or BBC Master microcomputer computer
(2)
ARM co-processor
(3)
A monitor
(4) A twin, double density, double sided, 5.25 inch disc drive
(5)
A Winchester disc unit with a suggested minimum of 10 Mbytes
capacity
(6)
Interconnecting cables:
The cable for the connection between the ARM co-processor and the
ACORN computer is supplied with the ARM co-processor. It is
captive at the ARM end with a connector at the other end for
attachment to the TUBE I/O socket on the ACORN computer
Otherwise, all the connections are made in the usual manner using the
standard cables supplied with each unit.
(7)
The software, all of which is supplied on 5.25 inch floppy discs, is as
follows:
•
ASSEMBLER
•
UTILITIES
•
