The first home of DPI was at 745 Distel Dr. in Los Altos (the picture is too dark to show well). Ironically, our row of offices is now an Allstate Office (remember they were our first major venture capitalist).  When the engineers started arriving we also had a place in Palo Alto because Los Altos did not allow even a soldering iron.   We connected both locations through a "new tech" cordless switchboard that kept disconnecting everyone.
