Was there life before computer?

calculating instruments before the digital era

In the schools

I like to present the old calculating devices in the schools, The youngster have to learn how to make simple operations with the slide rule, try the Addometer, the Addiator and a repro of the Pascalina.

I make speed competitions, Addometer against electronic calculator, but no chances, I win always! The Consul Monkey is a success: drove all the boys mad and is important that I caught the attention, after is more easy but the meeting with the teachers are more soft.
