Zayre Corporation was founded in 1956 by Stanley and Sumner Feldberg in Hyannis, Massachusetts as a discount department store chain. Zayre launched already in August 1975 the CONCEPT series of portable electronic calculators with the introduction of their first CONCEPT 24.
The Zayre CONCEPT Calculator Series culminated in June 1976 with the introduction of the Texas Instruments CONCEPT I, CONCEPT II, and CONCEPT III calculators based on the TI-1200, TI-1250, resp. SR-16 II but disappeared already in August 1979 with the clearance sales of the CONCEPT COMPACT calculators.
The CONCEPT 10 calculator could easily be identified as a rebadged Novus 750 with a slightly different keyboard color.
Dismantling this CONCEPT 10 calculator manufactured in May 1976 rebeals no surprises - the printed circuit board (PCB) of the calculator is 100% identical with the Novus 750.
The CONCEPT 10 calculator was introduced in March 1976 and discontinued already in January 1977 with the blow-out sales of the CONCEPT I, CONCEPT II, CONCEPT 10, and the 2nd and 3rd design of the CONCEPT 24 calculators.
