J’avais toujours eut envie de construire des robots, mais c’était une envie refoulée car l’approche traditionnelle à base de pièces détachées provenant de différents fournisseurs est très compliquée et demande un matériel important. Aussi quand j’ai vu la rediffusion du documentaire sur M6, j’ai été emballé, et 3 semaines après je sortais de la boutique du robot avec ma première boite de RIS sous le bras.

Welcome to the LEGO MindStorms RCX Hub! 👋

This BrickBot organization contains information and projects related to the original LEGO® MindStorms set—the LEGO® MindStorms RCX!

A hacker community grew around the RCX—individuals intrigued by the capabilities and determined to push the limits of what was possible. Of a time before GitHub came to prominence as site for sharing open source projects, many of these RCX projects were scattered on various personal and univeristy websites across the Internet.

A number of these projects have otherwise disappeared from the Internet, while others languished in deprecated version control systems or could only be found by looking up the website on an Internet archive. A few were projects that had been downloaded and saved before the original web pages disappeared, but whereever and whenever possible, links to either the original website (if still active) or an Internet archive version (if available) have been included.

Tools and utilities from dumping the ROM from an RCX, which is often then used by RCX emulators.

Obtaining a ROM Image

Based on both original instructions posted here and accessed via archive.org
as well as more recent documentation (plus a patch file) posted on the RCXSimulator site.

Here is one set of steps you might follow to obtain an image:

1. Get and compile send.c.
2. Get firm0309-modToGetROM.srec. You can have a look at the diff getROM.diff.
3. Download the new firmware file to the RCX. with nqc for example nqc -firmware firm0309-modToGetROM.srec
4. Get and perhaps edit getrom.pl. As is, this program assumes you are running under some flavor of Unix and that you have Perl 5 installed. It also assumes that the send program is in your path.
5. Run getrom.pl and redirect its stdout to a file. When getrom.pl completes, this file should contain an image of the ROM in s-record format.
6. Don't forget to reinstall the normal firmware once you've got your ROM image.
