Virtual SR PART 2
Wolf's Collection of Slide Rule Simulators
|
This is a composite gallery of simulated slide rules that may be manipulated on your screen by use of your mouse, as if the slide rule is actually in your hand. The Aristo models have readouts to show the value under the cursor. These were originally created by Derek Ross of Winnipeg, Manitoba Supplimental virtual creations and modifications were followed by Stefan Vorkoetter, Brian Bartholomew, Bob Roswell and Bob Denny.. ISRM is able to independantly host and preserve the simulator files due to the efforts of Bob Denny who compiled these selections from 2009 to 2016. The most recent expansion of these simulations were created by Dr. Robert P. Wolf in Australia from 2017 to 2020. Robert passed in June 2023. His work on Simulators being preserved on ISRM. The latest addition is that of the mechanical Curta Model II simulator, created by Robert Cailliau of Belgium.

Design Notes about this Page
Derek Ross' Original web site at http://www.antiquark.com and Bob Denny's modifications for local storage of images, have been edited to meet the ISRM format and security certificates and to add mobile friendly tags. It should be noted that the virtual slide rules were made possible by Walter Zorn's Drag and Drop for Images and Layers.
These pages should work in browsers that support JavaScript and W3C DOM standards. Unfortunately, the original simulations do fit or work on touch devices (iPad, Android, etc.).
