The archives are probably the most important and valuable collection of documentation and items in the world, covering mechanical accounting machines and early electronic developments. Archives of other companies are closed, have not collected documentation and items, or have been damaged or destroyed. Among the viewable items are cash registers, accounting machines, early calculators, Postronic machines, drawings, and electronic subassemblies. Some of the electronic subassemblies were invented for the NCR Bombe code-cracking machine. The archive is located at 224 North Sinclair Street.
Parking is available on the street.
Avoid parking in the Dayton Blueprint parking lot, as you will be towed. Some spaces may be available in the Wright State parking lot, but do not park in the county spaces. You must make reservations for dinner. Please read it.
