In 1986 Texas Instruments changed the design of the "Slanted Calculators" slightly. If you compare this TI-56 with the previous TI-56 focus yourself on the position of the TI logo.

We know from other TI consumer products like the entire Speak & Spell line a similar movement in the corporate identity during the year 1986.

TI-55-III_Switch.jpg (21749 Byte)Between 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.
