Digital Den, in Cambridge, Mass., is a relatively new organization, having started up in early 2013. Founder Mary E. Hopper says, "Our purpose is collecting, preserving and exhibiting a wide range of computing systems -- primarily personal computers -- in their original 'living' state for the public to experience and enjoy first-hand. There is a special emphasis on computing in the New England area."
As of September 2013, Digital Den had already accumulated about 1,000 items, estimates Hopper, all of which are on display. "We have machines from Apple, IBM, TI, Toshiba, Sony and others," she says.
How to donate: Digital Den's wish list includes things like a Xerox Star 8010 "Dandelion," a Nintendo Power Glove and a Sun Workstation with HyperNews.
