It's referenced in the ACM digital library:

But being a paper from 1986 there is no pdf of it there (not even a scan of a hard copy as is the go with older papers).

Oddly, there is no reference to it at all in the ieee digital library.

As a paper from 1986, I'm not sure of the chances of it being in any library is. It certainly isn't in the [Swinburne University] one...

So I'm all outta ideas.
