C MM D RE AMIGA 500 / 2000 DIAGN STIC (PAD
First read this manual completly.
This package inc udes everything to perform an AMIGA diagnostic test, exept the
C64 PSU and A501 needed to test an AMIGA 500. This test checks a RAM, every
port, the four sound channe s and video of the AMIGA 500 and AMIGA 2000, but it
does not check the expansion-s ots of the AMIGA 2000.
Note: This test is for service only!
Make sure that you have got a of these parts:
CONTENTS:
1 AMIGA DIAGNOSTIC BOX
1 AMIGA DIAGNOSTIC MODULE
9 AMIGA DIAGNOSTIC CABLES
1 AMIGA DIAGNOSTIC DISK
1 AMIGA DIAGNOSTIC USER GUIDE
1 DISK "PC TERMINAL EMULATION"
Warning: Before connecting or disconnecting anything to / from an AMIGA
please make sure that the AMIGA system is switched off.

How to use the AMIGA DIAGN STIC KIT
You can run this test either from diskette or from ROM, depending on what you
prefere: If you do not want to open the AMIGA 2000, use the AMIGA DIAGNOSTIC
DISK ( A.D. DISK ), but then a part of the CHIP-RAM can not be tested.
The ROM-based test resides comp et y in the AMIGA DIAGNOSTIC MODULE
(A.D. MODULE), so the test wi start even if the machine is fau ty. Additiona y this
test checks a CHIP- and FAST-RAM.
To run the ROM-based test:
- A500 on y: insert A501
- connect the AMIGA DIAGNOSTIC (A. D.)BOX with the AMIGA
- optiona : connect a termina to the A. D. BOX
- insert the A. D. MODULE
- connect power to both A. D. BOX and AMIGA
- set the switch on the eft side of the A. D. BOX to A2000 or A500
- turn power on
To run the disk-based test:
- A500 on y: insert A501
- connect the AMIGA DIAGNOSTIC (A. D.)BOX with the AMIGA
- optiona : connect a termina to the A. D. BOX
- connect power to both A. D. BOX and AMIGA
- set the switch on the eft side of the A. D. BOX to A2000 or A500
- turn power on
- insert the A. D. DISK at Workbench-prompt
For detai ed information see chapters be ow.
To run the test, you have to connect the AMIGA DIAGNOSTIC BOX (A.D. BOX) to
a power supp y. You may use a C64 PSU ( testing an A500) or you can connect it to
the FDD-PSU-Connector of an A2000 power supp y (see chapters be ow).
The A.D. B X does not supply the AMIGA-PCB with power nor does the
AMIGA-PCB supply the A.D. B X.
Press the RESET BUTTON on the A.D. BOX, if the test does not start correct y.
The test finishes with an a ternate disp ay of two test screens on the monitor and
running numbers disp ayed on the LEDs at the A.D. BOX.

When an error occurs, a two digit hex number is disp ayed on the LED disp ay on the
A.D. BOX. This error code indicates which test fai ed. You find a comp ete ist of a
error codes in the AMIGA DIAGNOSTIC ERROR TABLE.
Connecting the AMIGA DIAGN STIC B X
You have to insta seven cab es between the A.D. BOX and the A500 / A2000. You
can distinguish these cab es by the connectors of the cab es:
1. ne cable for the internal Disk Drive:
This cabe has a 35 pin SUB-MINI-D (SMD) ma e and a 35 pin card edge connector.
P ug the 35 pin SMD into the connector abe ed "Disk Drive intern" and connect the
other end to the interna drive connector.
2/3. Two identical cables for Serial and Parallel Port
These cab es have both a 25 pin SMD ma e and 25 pin SMD fema e connector.
P ug the first 25 pin SMD ma e into the A.D. BOX-connector abe ed "Seria Port",
the other end into the seria port of the AMIGA ( short cab e).
P ug the second 25 pin SMD fema e into the A.D. BOX-connector abe ed "Para e
Port", the other end into the para e port of the AMIGA ( ong cab e).
4. ne cable for the external Disk Drive:
This cab e has a 23 pin SMD fema e and a 25 pin SMD ma e connector.
P ug the 25 pin SMD (ma e) into the A.D. BOX-connector abe ed "Disk Drive
extern", the other into the externa disk drive connector of the AMIGA.
5. ne cable for the Keyboard:
A2000: use the cab e with 9pin SMD fema e and 5pin DIN connector.
A500: use the cab e with 9pin SMD fema e and 5pin f at connector.
P ug the 9 pin SMD (ma e) into the A.D. BOX-connector abe ed "Keyboard", the
other side into the A500 / A2000 keyboard connector.
6/7. Two cables for both Mouse/Joystick-Ports
These cab es have 9 pin SMD fema e connectors on both sides.
P ug one of the SMDs into the A.D. BOX-connector abe ed "Mouse / Joystick 1", the
other end into the port where norma y the mouse is connected.
Connect the other mouse/joystick port with the other cab e to the A.D.
BOX-connector abe ed "Mouse / Joystick 2".

A2000: Inserting the A. D. M DULE
If you want to run the ROM based diagnostic, you have to insert the AMIGA
DIAGNOSTIC MODULE (A.D. MODULE).
Be sure to turn off a power, and open the Amiga 2000.
Insert the A. D. MODULE into the MMU connector next to the CPU in the same way
you insert any other AMIGA expansion cards ( abe ed side facing the PSU-subchassis,
see picture be ow).

A2000; Connecting Power
To run the test, you have to connect the A.D.BOX with a power supp y: connect the
A. D. BOX to the FDD-PSU-connector of the A2000 PSU.
NOTE: the A2000 PSU needs at east 30% of its nomina oad to work correct y, so
connect the mainboard to the same PSU.
Make sure that the power supp y is switched off when you connect it to the A.D.BOX.
Both, AMIGA and power supp y, have to be connected to your oca net as we . The
A.D.BOX. does not supp y the AMIGA with power nor does the AMIGA supp y
the A.D.BOX.
