 | | use RCX with the lego set 4095

I wonder if anyone has experience with this set. The description on the lego site is not clear enough for me to determine whether I can replace the body with the RCX... Thanks! ---...--- -------- Elizabeth (19 years ago, 24-Nov-05, to lugnet.robotics.rcx.legos)

(...) Can you post the output generated by NQC when you add -v to the command line? nqc -Susb -TRCX2 -v -d filename.nqc > output.txt Or you could just email it to me directly. John Hansen (19 years ago, 24-Nov-05, to lugnet.robotics.rcx)

(...) Ok, your right they are separate, so that if I left the second -Susb out, my program wouldn't download via the USB tower, but would go to my other RCX via the serial tower. My batch-file is this: nqc -Susb -firmfast c:\newrcx~1.lgo nqc -Susb (...) (19 years ago, 22-Nov-05, to lugnet.robotics.rcx)

Hello, I'm trying to get a recent brickOS (0.9.0) working on Mac OS X 10.4.3. I have an RCX 2.0 with the USB tower. I have a cross-compiler (gcc 3.2.2) that apparently works, and using the firmware download program included with lejOS (specially (...)

I have swapped over the towers. The USB worked perfectly in (...) (19 years ago, 21-Nov-05, to lugnet.robotics.rcx)
