One of my favorite reference magazines was Mini-Micro Systems which published from 1976 to 1989 by the Cahners Publications. They printed 10 issues a year along with a Spring and Fall Peripherals Digest. I think Starting in June 1984 they printed a Mini-Micro computers special issue. I have one copy left, the 1983 Fall Peripherals digest. It is what I was looking for when Jerry was trying to identify the CDC/QD drive he had. Unfortunately the model numbers and what is printed on the drive don't correspond (and from what I remember never did)
