CALCULATING MACHINES

It was not until I moved my office recently that I realized that I had accumulated a fair collection of pre-computer machines, and thus became more interested in calculators.

• The History of the Abacus
• For a quite good history of calculators see Erez Kaplan's page.
  
• The International Association of Calculator Collectors is building a new collection of web pages.
  
• TI's history of the development of the first hand-held calculator.
  
• The HP Museum.
• There is an excellent collection of mathematical artifacts under the title "cut the knot" that include:
  • The Abacus
  • Napier's Bones - an early form of calculator
