ParallelPort Reader

CardReader specifications
First have a look at the result. What you are going to build will look like that: (These are Timo Hegemanns and Rene Reichardt's versions.)
Well. You are ready? So let's go:)

The connector

First there is the MemoryCard connector! Either you are lucky and you find a damaged PSX or MultiTap (then you can extract the connector), or you have to build it! You need an old slot (old PC main board, we do not destroy any Amiga board!!) or an 5"¼ floppy disk connector. This slot must be modified:

The hardware
All what you need is: The home-made MC connector :) An external power supply A 25 pin male connector 4 resistors (see pic) 2 LM317 Some cable A soldering iron Some patience:)
Well, the following pic contains all the needed info to build the interface. On the top left pic, each number refers to a pin on the disk port connector (left column) or on the MC connector (right column). Don't forget to connect all GNDs together!

External power supply

The parallel port reader requires an external power supply, but there should at least one around to use a while (Discman, Walkman, Mobile, Dart board, ...). The external power supply should be about 9V-18V. The exact voltage isn't important because the LM317 is creating always the correct value by using the resistors. The power supply should be able to output more than 200mA! The output of a Playstation itself isn't more than 100mA per powerline, but the LM317 circuits are consuming some energy, too! If you are only using 15 block cards then 100mA should be enough!  Do not use power supplies with less than 100mA! They may work, but they are producing much heat and may burn out!

Multi slot version

This picture shows how to build a multi slot version!

Information

The pictures alone should allow you to build the interface. Just click here if you want to read additional information anyway.
