Canon Canola 167 Desktop Calculator

Canon Canola 167

The Canon Canola 167 is a rather unique machine, as it utilizes a small magnetic drum for its main register storage. Other machines of the era utilize recirculating magnetostrictive delay lines, chains of shift registers or ring counters, or magnetic core memory. The fact that the machine uses a magnetic drum is reflected in the calculation times for the machine, with division operations quoted as taking up to one second.
