Made in the USA., and sold in Britain under the Sumlock name, and in the U.S. and elsewhere under the Monroe name or just Compucorp. This is one of a series of machines for different purposes. The journal "Electronics", for December 6, 1971, on their introduction, said of this series - "Each machine is "microprogramed" with MOS/LSI logic specifically for each application. ROMs produced by Texas Instruments and AMI to Compucorp specs control the keyboard functions pre-programed by the manufacturer. Groups of calculators bearing family names such as Statistician, Scientist, Accountant, and Treasurer, are thus tailored to the user." Although placed in the Desk Calculator section these have a battery compartment and can be operated remote from the mains AC supply using 4 D-cells. However, although they are portable, they are hardly pocket calculators ! These high-quality programmable calculators looked very futuristic when they appeared with their smart and business-like design. Inside, a great deal is squeezed into a small volume, yet everything comes apart and goes back together very easily for servicing. Within a couple of years the IC manufacturers where cramming all these functions into 1 or 2 ICs, the cost of the competition plummetted, and the size shrank.. Price: U$S150 plus shipping.
