I didn't say anything was wrong with it. You win, someone who wants an extra RCX wins, someone who wants a pile of technic parts wins, and the seller wins! Even Lego wins, because they sold another Mindstorms system. Lego could win more by giving us (...) (23 years ago, 11-May-02, to lugnet.robotics)

(Accidentally replied to the poster, rather than the group earlier.) Yes, I understand what is being done...

Seems to me that the BEST implementation of the RCX would be for some CORE changes and feature sets to be built in. I realize that these would be somewhat expensive, but I would pay pretty good money to have an RCX with the following specs (built (...) (23 years ago, 10-May-02, to lugnet.robotics.rcx)

I've seen those. I think what someone does is buys a mindstorms set, and breaks it up into these parts: - 2.0 upgrade stuff (CD, IR tower, instructions, and test pad) ($20 to $40) - RCX ($80 to $100) - Non-electric stuff (the legos) ($50 to $75) I (...) (23 years ago, 10-May-02, to lugnet.robotics)

Can someone using the egcs compiler suite test the following code? It seems it doesn't compile under egcs. int main(int argc, char *argv[]) { double foo = 1.0; return foo > 0.1 ? 0 : 1; } Compiles fine under gcc 3.0.3. Regards, Michael (23 years ago, 10-May-02, to lugnet.robotics.rcx.legos)
