This claims to be a version from 1980. It appears to have scans of the illustrations from 1980, but retyped text.
Thanks. That's sufficient for my curiosity: Good lays out the argument for lots of aliens (which is cogent enough and time has vindicated various beliefs such as planets being common), notes that galactic colonization is easy and highly certain on astronomical timescales, that there must be a stable governing structure (the Chief Entities, who may or may not be FAIs), and argues that the reason for the Great Silence is the 'zoo hypothesis' (just with FAIs).
Not too unreasonable for the time period - as he notes, the first SETI searches had just been done and parapsychology still seemed fairly credible then - but I'd say by this point it's pretty clear that there are no intelligent aliens whatsoever and the zoo hypothesis is untenable, and parapsychology likewise. So a historical piece of minimal general interest.

Over the last year, VincentYu, gwern and others have provided many papers for the LessWrong community (87% success rate in 2012) through previous help desk threads. We originally intended to provide editing, research and general troubleshooting help, but article downloads are by far the most requested service.
If you're doing a LessWrong relevant project we want to help you. If you need help accessing a journal article or academic book chapter, we can get it for you. If you need some research or writing help, we can help there too.
Turnaround times for articles published in the last 20 years or so is usually less than a day. Older articles often take a couple days.
Please make new article requests in the comment section of this thread.
If you would like to help out with finding papers, please monitor this thread for requests. If you want to monitor via RSS like I do, many RSS readers will give you the comment feed if you give it the URL for this thread (or use this link directly).
If you have some special skills you want to volunteer, mention them in the comment section.
