Calculators Sold by Sumlock And Made By Other Companies
Wanderer Conti
Wanderer Conti
A listing electronic calculator, manufactured by Wanderer in Germany and sold by Sumlock Comptometer. The electronics was made by Nixdorf which bought Wanderer in 1968.
The Wanderer Conti was introduced in late 1964 and was the first electronic desktop calculator with printing output. It was added to the Sumlock Comptometer range in late 1967, since there were then no Anita models with printer.
Prices started at £298 Sterling (about US$750).
John Clements worked as an engineer at Sumlock from 1958 to 1978, and was one of the first to train on the Conti. He says: I found the Conti machine very unreliable and the mechanical section especially so.
If you have further information about the Conti (especially photographs), the development of Anita calculators, or know of somebody who worked there, please get in touch with me .
