- 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.
