|
I've written replacement firmware for the RCX with the objective that it is compatible with Lego's byte-code opcodes. I'm looking for volunteers willing to give it a test and provide feedback on any problems/bugs. Please send me a private e-mail if (...) (20 years ago, 7-Nov-04, to lugnet.robotics) !

(...) Hello Dick, That sounds great, almost too good to be true (especially for the 100x version!) Would you have also a modified NQC version to enable new features? Philo (20 years ago, 7-Nov-04, to lugnet.robotics)

Uhmm... I get the impression that you're not intending to open the source code to your replacement firmware, but I'm not sure if that's a particularly good idea for something like this. I suspect that the "hacker" mentality that drove the creation (...) (20 years ago, 7-Nov-04, to lugnet.robotics)

(...) Wow, I'm impressed and interested. Unfortunately it's our busy season for work and I won't get a chance to play with my Mindstorms for a couple of months. But I look forward to seeing this progress! Dean (20 years ago, 8-Nov-04, to lugnet.robotics)

(...) I hope you didn't took the "too good to be true" as a criticism - it was only an amazement mark!. BTW, is the 10x version a slow down of 100x one, or is it an older, less optimized version? (once again, I'm not criticizing, I fairly well (...) (20 years ago, 8-Nov-04, to lugnet.robotics)

Hi Dick, Congratulations on your fabulous effort! I'm always pleased to find out about people who can get down and dirty at the hardware/software interface. Had you thought about the community developing a test plan for verifying LEGO firmware? (...) (20 years ago, 8-Nov-04, to lugnet.robotics)

Will there be a collaboration to sort out the mesh with NQC? This is simply great stark news and very exciting stuff, and we do pass along a 'congrats'! Nonetheless, we urge (and will contribute whatever we can) towards the move to use NQC, as or (...) (20 years ago, 11-Nov-04, to lugnet.robotics)
