All, I've finally got around to updating my site with a detailed description of connecting the NXT to a Bluetooth GPS unit. It updates the NXT display in real time with lat, long etc. The parsing is really barebones and shows the power of pbLua in a (...) (17 years ago, 2-Jul-07, to lugnet.robotics.nxt)

Hi all, Do I need to add a JTAG port to develop an alternative runtime for the NXT? We did the RCX without this level of debugging, and the NXT is far more open.

Here's two things to try since you've only swapped out the VM hich I assume is a replacement for the "c_cmd.c" file. 1. First there is a "#define" that specifies the start address of the file system.
