In 1986 Texas Instruments changed the design of the "Slanted Calculators" slightly. If you compare this TI-53 with the original TI-53 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.

Don't miss the TI-53 manufactured for Zenith Data Systems..
