CD32 connection hacks
Daniel Pfund
April 10, 1995
Abstract
This text file describes:
o How to connect the CD32 with your Amiga;
o How to connect the CD32 with an Amiga 2000 style keyboard.
But before you read further, please note that you still do need a
CD-ROM to be able to boot the CD32 and communicate with another
computer. In my case I used the Network CD from Almathera.
1 Disclaimer
I (Daniel Pfund) wrote this file purely to help other people to connect
their CD32 with other peripherals. I am glad to help, but I am in no way
responsible if you destroy/dammage your CD32 while attempting to make these
connections. I have tried to keep the information as accurate as possible,
but if you find an error, please contact me immediately! (see section 5
"Author" for the addresses where you can reach me).
Also please note that although this is no way a major electronics
project, you should at least know how to solder correctly! Don't attempt
this if you have never soldered before . . .
2 Introduction
As you read in the abstract, this file will describe how to connect several
items to your CD32. I wanted to list here some other references you might
find useful (that's where I got the information from).
1. The CD32FAQ. You can get it by FTP at: "ftp.demon.co.uk:/pub/amiga/
info/cd32-faq.txt". This is really the main reference and you will find a
huge amount of information here. The only problem being that it is very
difficult to access the FTP site, even at non prime time hours.
2. Article posted by Anders Stenkvist (ask_me@elixir.e.kth.se) called "CD32
expansion port info". It has all the pinouts you need, but contains at
least one error (the one I've found!), so I don't know if the rest is
correct . . .

3 Parts needed
The following parts are needed:
o 1 MAX 232
o 1 16 pin IC socket (optional)
o 4 1 microF elctrolytic capacities (or 10 microF goes also) rated 16V
o 1 mini DIN 6 poles male
o 1 DIN 5 poles female
o 1 DB-25 female
o 2 m (more or less) of 2 conductors (+shield) wire
o 20 cm (more or less) of 5 conductors (+shield) wire
o 1 led (optional, see section 4)
o 1 330 ohm (or 470 ohm) resistor (optional)
o 1 box to put the whole thing into (optional . . . )
All the parts should be available at your local electronics store and the only
costly part is the MAX 232 (~ 6$), and all the parts would cost you about 12$.
4 The cable
Once you have got all the parts you need, you can start putting them
together following the accompanying schematic in the IFF file.
The way you do this is entirely up to you. All you have to do is
connect together the pins with the same name. You can do it very easily on
a piece of veroboard or completely professionaly on a circuit. I've not
provided the PCB plan, but it is not very difficult to invent one.
As you can see, you can add a led to check if the CD32 is on and
everything is working fine. This is absolutely not mandatory. You will
just need an extra led and a resistor to limit the current going through
it.
