Early Anita Desktop Calculators

Anita Mk 11


9-digit display.

A low-cost version of the ANITA Mk 12 (with reduced display capacity), introduced after the Mk 12, costing £298 (about US$ 710).  Few details of the electronics of this machine are available at the moment, but it appears that it has a hybrid of cold-cathode tubes (including a Dekatron) and transistors.

Introduced in 1968.

Price in 1968: £298[1] (about US$710).

There is an operating manual for this machine in the Operating Manuals & Leaflets section.
