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.
This CONCEPT VI calculator was introduced probably together
with the CONCEPT V or shortly after it and is what we refer in the Datamath
Calculator Museum as Far East Generic Design
II. Don't miss the MYSTERY
CONCEPT VI.
Dismantling
the CONCEPT VI reveals no surprise - the printed circuit board (PCB) of the
calculator is already known from e.g. the Texet
880. Please notice the "880" designation etched in the pattern of
the printed circuit board (PCB) next to the REV B marks.
Fellow collectors - if you own a Zayre CONCEPT calculator, please report us the serial number and
date code from the back of the calculator
for our Database.
