I read the issue at the Imperial College library in 1986, and ever since have been frustrated that it's simply not available outside of institutional libraries apart from some material reprinted in the August 1996 issue of Byte.

I finally found a copy on eBay some months back, and just got the courage to take a scalpel to the spine of this thirty year old classic in order to make a legible scan. I've posted a 171 page 90MB pdf suitable for double-sided printing, and the original 300dpi scans.
