Didn't find the paper, but did find:

"The UNIX operating system environment has found wide use in a variety
of time sharing, word processing, and data processing applications.
Until recently, it was only available on single processor computer
systems but now has been successfully emulated by D. L. Bayer and
A. M. Usas on a nonstop multiprocessor computer system built by the Tandem
Computer Company"
