In the year 1986 the design of the 2nd generation slanted calculators was slightly changed:
• The TI logo moved from bottom left to the top right of the calculator
Compare this TI-57 II with its predecessor here.
We know from other TI consumer products like the entire Speak & Spell line a similar movement in the corporate identity during the year 1986.
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.
