PetManimal writes "Computerworld has gone back through forty years worth of magazines, and came up with some entertaining IT-related advertising gems from decades past. Highlights include The Personal Mainframe, an image of the earliest screenless briefcase portables, and Elvira hawking engineering software. From the article: 'Remember Elvira, Mistress of the Dark? Besides appearing on TV in features like Elvira's Movie Macabre Halloween Special, Elvira also invited Computerworld readers to "cut through paper-based CASE [computer-aided software engineering] methods with LBMS" software. "The scariest thing about CASE is the several hundred pounds of books that land on your desk and for which you've paid fifteen gazillion dollars, when you buy off on a CASE development methodology," she writes. Can you guess what year Elvira appeared in this Computerworld ad? Headline hint: "IBM delays notebook arrival in U.S."'"
