A blog by Vikram Shah about pencils, typewriters, and other(non)related interests.
Interesting. Very nice slide rules. I have a few myself although I do not collect them. I needed them for high school and my first semester of college. Slide rules always were and still are fascinating. Every so often I get one out and use it and to really cause confused looks I'll take one to work and use it there. There is abundant information on using slide rules on line too.
I collect them too but they are harder to find than typewriters. My favorite is the 909-ES with metric conversions on the back. someone has set up a virtual one here:http://www.antiquark.com/sliderule/sim/n909es/virtual-n909-es.html
