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 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.
