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 Original Equipment
Manufacturers (OEMs) in Far East, moving 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.
