Has anybody dared to ask Freescale Semiconductor for it? Or permission to make it available for download?
From what I hear, Freescale Semiconductor owns the rights to Codewarrior. The only remaining versions that they support are the versions that they're giving away for free. They might be willing to make the older versions available for free as well, with the caveat that they will provide no support for it, no guarantee as to its fitness for any use, and that they assume no liability for any consequential or inconsequential damages arising from your use of it -- whatever restrictions they choose to impose. Don't know if they would allow you to do that, but the worst they can do is say no. So why not just send them a letter or something and ask?
