A gallery of clickable simulated slide rules.

This one is complete with a numeric readout of the cursor position! It's really useful if you're unfamiliar with reading the various scales. Here is the link to the original web page for this simulator, as well as Stefan's Historical Computing Devices.
If you're not sure about how to use a slide rule, take a look at Slide Rule Calculations by Example. It's a self-guided demo that demonstrates different calculations by simple examples. Also included is How to Use Your Pickett Slide Rule, a simple 4 page manual (scanned in 4 images).
This package allows you to run Derek's Virtual Slide Rule Gallery self-contained on any computer, without an internet connection. It's perfect for putting on a USB drive. This web page has been edited to make it a bit more modern in appearance, to remove the user comments and external links (except the Aristo 970 one which I have also made part of this package), and text and style changes as appropriate. I also added Brian Bartholomew's Virtual Slide Rules and slide calculators as of February 2016. All of the virtual rule pages have been made identical in style, and they now share a single style sheet and a single copy of the (modified and updated) wz-dragdrop script. If you want to see the original page and the stuff that is there, you do need to be connected to the net, then just go to Derek's original site. 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. As of February 2016, it should work in your browser unless you are a serious Luddite and haven't updated your browser in many years. Unfortunately, these simulations don't work on touch devices (iPad, Android, etc.). There is hope... Bob Roswell over at The Computer Museum has edited the Pickett N3 so it's usable on a tablet. The page can be found HERE. Hopefully soneone will figure out how to generalize this to all of the simulations here. It uses a completely different HTML5/JQuery method for animating the rule. Finally, Timothy Scott has converted the N600-ES rule to an Android app so it can run on smart phones. Now the virtual N600 is truly as portable as an analog original. The app can be downloaded HERE.
