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.

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.
