In my first tutorial I mentioned that my 5 pin ribbon completely broke off. In order to go any further I need a keyboard for my Speccie. I had an old PC keyboard laying around, which I wanted to use to build a Guitar Hero Guitar. For this I only needed the chip with the surrounded components.
I don't have pictures of me showing you how to disassemble a keyboard, but there are many tut's on this site that does.
After I removed all the key's of the keyboard I laid the original rubber keypad over the corresponding key's in order to make a new keyboard. With a jigsaw I cut out the desired PCB and rebuild the new keyboard according to the original membrane print.
After hooking it all up and testing my new keyboard I could call this a success.
