Footprints on the summit are soon blown away, but each of these items made their mark briefly for those who cared at the time, so remain worth revering. In Jul. 1975 the first computer store opened (in L. A.). In Mar. 1976 Albuquerque hosted the first World Altair Computer Conference (see no. 8) and by then, even novices knew something was happening. And I note that the word “something” as I’ve used it in the last sentence has no synonym.
