Xah Lee's Unixism

[Pfhreak]

Patrick,

I maintain the web page that Rupert mentions in responce to your message
about Nextstep and Mach. 
(http://www.macos.utah.edu/Documentation/MacOSXClasses/macosxone/unix.html)

I'm curious to learn more about the development of Mach and its use in
Nextstep.  Can you point me to your sources -- preferably online so I can
put them in the Bibliography section -- especially those that mention when
Mach was turned into a Microkernel?
