All, Doug McIlroy sent me an e-mail about the late Mike Mahoney's project
to create an oral history of Unix. His documents are at
http://www.princeton.edu/~hos/Mahoney/unixhistory
I've taken the liberty to mirror them into the Unix Archive and they are
now also at
http://minnie.tuhs.org/Archive/Documentation/OralHistory/
Cheers, Warren
