Ca. 1955, my father's secretary's 10-key, tape-printing, adding machine (judging from the aesthetics, I'd put it about 1950), used the diamond lozenge for subtotal, and the square lozenge for total. On the other hand, ca. 1959, the diamond lozenge was not found on the widely used IBM 1401 computer, but the square lozenge was. The same is true of the 1949 IBM 407, the last and best of IBM's sub-computer machines. -- John W Kennedy "The whole modern world has divided itself into Conservatives and Progressives.
