I'm learning about IDEs and software development on Mac OS Classic systems and recently discovered Macintosh Programmer's Workshop. Navigating to a cached version of the old MPW Tools page on Apple's dev site, this IDE appears to have been made available for free on Apple's FTP server after it was superseded by CodeWarrior.

Are there any resources or downloads available of MPW? Or do I have to find an old Developer CD matching the Mac OS version I want to use MPW on.
