You're absolutely right about 1980s; it's from the Trek zine One Way Mirror. And given the fact that the body type appears to have been done on an IBM Selectric, I'm betting it's letterpress.

But I think I've nailed it down, with the help of whatfontis.com. The first time I tried that site, I gave it the one-line file that another site insisted on. This time, I gave it both lines, and it came up aces. It's almost a perfect match with Rustikalis DT Light. My sample is wider than the online version, but the letterforms are exactly right.

Unfortunately, it's not one of the fonts I own. You, by any chance?
