In Tokyo in 1964 I bought a Soroban with Kojima’s book "The Japanese Abacus: Its Use and Theory". An event that sparked my interest in abaci ... and in .

After getting my M.Eng.(Elect.) at Cornell, my 30 year career included working on the design and of nuclear , missile systems , and industrial and engineering computer systems sales and .

Deciding to become a high school math teacher at the end of 2000, I took a History of Math course as part of my M.Ed. Program at UMassLowell. I was struck by how easy it would be to use ancient Roman, Greek, Egyptian, and Babylonian numerals to record abaci calculation results. Prof. Gonzalez said, "Yes, but how would you do multiplication and division?"

So as a hobby, I've worked the last 10 years to (re)discover the schematics and rules of the the Ancients used to do their accounting and engineering to support and empower the greatest empires in human history.

I hope you find Ancient Computers interesting and useful,

Steve Stephenson, M.Eng.(Elect.), M.Ed.

P.S.: Before you edit Ancient Computers, please be sure you read and understand the whole article and the Works Cited, and have watched and understand all of Stephenson's videos.

P.P.S.: Also available are paperback and eBook versions of Ancient Computers with essentially the same content (see Paperback, eBook, "How to Use", and "How Romans Used"). Because it's much easier to modify, updates will show up on IEEEghn.org first.
