Would this do?  FYI, it's about 50 pages, including a four-page bibliography.

An Architecture for Interprocess Communication in UNIX*
-- DRAFT of June 22, 1981 --
William Joy and Robert Fabry

Again, I scanned the paper and then Paul aggregated the scans into a single PDF.
It should be available here:
