My biggest gripe about spirit is that it is only available for Win32. If
it had also been available on Mac and Linux I would've layered NQC on top
of it and never had to create a non "LEGO sanctioned" interface to the
RCX. Actually, TLG now appears to acknowledge NQC as a legitimate way to
develop for the RCX - at least that's how I interpret their change to
allow NQC programs to be directly uploaded to www.legomindstorms.com.
Yes, spirit has a definite advantage when you're building something where
part will run on the host computer and part will run on the RCX. NQC is
really only intended to craft software to run on the RCX itself.
Bottom line: I'm all for a variety of tools. The "best" tool is the one
that fits comfortably in the hand of its user and is effective for present
task. Given the variation of both tasks and hands, its unlikely that any
single tool will be perfect for everything.

I doubt that LEGO would depart too far from their opcode protocols when writing their SDK, especially as it's designed for advanced users, and the syntax of the language seems to mirror assembly. From what I've seen, the Spirit OCX (...) (25 years ago, 23-Dec-99, to lugnet.robotics)
