Introduction

How to take the top (yellow) and bottom (green) case halves off the RCX 1.0. Once you've taken off the case, you can clean the electrical contacts and replace any fried electronic components.

This guide is based on Kekoa Proudfoot's instructions on his RCX page, which includes two sentences of disassembly instructions and some photos.

Remove the buttons from the top case. (They probably fell out already.) Squeeze the clips at the top and bottom of each Lego 9V connector. Push them through.

Conclusion

To reassemble your device, follow these instructions in reverse order. If you bent the battery clips when you removed the circuit board, bend them back down so they make contact with the solder on the board. The orientation of the gray battery cover doesn't matter.

As you can see, I was rushing when I did this guide. I'm planning to redo the disassembly next weekend and take landscape-oriented photos with better lighting and a white background.

It’s a GREAT guide, thank you! I bought an RCX off Ebay and found batteries inside that expired 6 years ago. You can imagine the corroded mess I’m cleaning up. Thanks to your guide I have it apart and cleaning.
