Saturday, January 13th, 2007This is half-calculator, half abacus (actually a soroban), which I saw in the Arithmeum in Bonn. Seemed a bit odd to me.
Arithmeum is interesting if you’re interested in counting machines – from the very earliest reckoning tables and abaci through to microchip design. I found the older items more interesting, the modern calculating tools aren’t of so much interest. Well worth a visit, though.
