of the TI-57 II was shifted in 1985 from Taiwan to
Italy. The internal construction was completely revised, instead a rigid Printed
Circuit Board (PCB) of the Far East calculator we noticed a flexible PCB.
In 1986 Texas Instruments changed the design of the "2nd generation slanted calculators" again. If you compare this TI-57 II introduced in the year 1985 with the later TI-57 II (1986) focus yourself on the position of the TI logo.
1985 and 1986 Texas Instruments created an amazing number of different designs
in the "Second Generation - Slanted LCD" calculator series just by
moving production to far-east contract manufacturers, fetching manufacturing
back to their own facilities and revising the design. Please click on the
picture at the right as a switchboard to all known versions of the Second
Generation Slanted LCD calculators.
