Bob Frankston co-created VisiCalc, the first spreadsheet for personal computers, and he serves alongside me on the board of the IT History Society. Brandon Vogel, our Secretary and Treasurer, joined me at Bob’s office in Newton, Massachusetts, a wonderfully crowded workshop full of hubs, routers, 3D printers and spare parts. We talked through topics for an upcoming ITHS panel discussion that Bob will lead, and along the way Brandon got his hands on a vintage Anderson Jacobson acoustic coupler.
