Introduced in the mid-1920s, the Burroughs Portable Adding Machine was intended to replace the earlier Class 1 adding machine. The Portable was designed by Alan A. Horton, who had previously designed the Burroughs Calculator, a direct competitor to the popular Felt & Tarrant Comptometer. The Portable has a modular internal construction, allowing for a wide range of feature variations. Portable models were available in Class 8 (addition only), Class 9 (addition/subtraction) and Class 10 (bank teller and receipt functions), with six, eight or ten columns, decimal or non-decimal systems, and motorized or hand-cranked variants.<br>Add it all up and take away the bullchit and what you have is a genuine piece of American History. They don’t make these any longer and there’s gonna be a day real soon when they’re as hard to find as an honest politician. True words!
