The calculator section is divided into 4 groups:

  1. Slide Rules
  2. Mechanical & Electrical Adders and Calculators
  3. Micro Computers
  4. Misc. Items (Early main-frame artifacts, manuals, etc.)
Click on the buttons above the gallery to switch groups. To see a larger image of a slide rule, just click on it.


Over the years, I have accumulated a few micros--about 100. For the time being, they are just stacked up in the garage waiting for some attention!
