The LEGO pieces you get with the Ultimate Builders Set are a nice addition to any collection. However, the software with all the instructions for all the models only runs on the PC. All the behaviors are completely possible with Robolab but without (...) (22 years ago, 9-Dec-02, to lugnet.robotics.rcx)

We use Robolab software and the RCX on our Power Macintosh G3. Will the Ultimate Buiders Set work for us in that environment? Dean (22 years ago, 8-Dec-02, to lugnet.robotics.rcx)

Hi Pieter, I'll take a shot at it... It's possible you may be experiencing a transmission problem on the RCX side. That's not to say that your RCX can't transmit IR data correctly... obviously it can since you are able to download BrickOS and that (...) (22 years ago, 4-Dec-02, to lugnet.robotics.rcx)
