I am building a device similar to the dexdrive, called the PlaySaver. I got the instructions from the [URL deleted as it didn't comply with forum rules], but instead of using a ribbon cable to create the plug for a memory card, I want to use the memory card slot from an old Playstation I have.

The problem is, I don't have the schematics, and can not find them anywhere, so I am asking if anyone knows of a site that has it, if you could post it here, it would be greatly appreciated, Thanks.
