Mark's Calculator Collection
I've been seriously collecting calculators for a few years now, but my interest in them dates back to my high school days.� In a not-insignificant way, it was my early obsession with calculators that led me into a career in mathematics.

Most of the collection, as it currently sits in my office.� Click here to see a larger (and clearer...) image.�� Lots of desktop calculators are scattered elsewhere in my office, on pretty much any flat surface that'll take them.� Seven historically-significant calculators (Sharp EL-8, Texas Instruments Datamath, TI-59, and TI-30, Hewlett-Packard HP-35 and HP-67, and Casio fx-7000) are on display in a hallway showcase in Albion's remodeled science complex.

Note: All calculator photographs on this site are my personal work, are not in the public domain, and may not be reproduced on the Web without my advance consent.� (Email me directly if you wish to use these pictures--I am not an unreasonable person and will probably grant permission readily, subject to a few simple common-sense restrictions.� Truth be known, I'll probably be excited that someone actually wants to use them.)
