The first design of the TI-35 looked really cheap with the black top and black keys. Texas Instruments corrected this design flaw and created this nice calculator, which was replaced in 1985 by the TI-35 II

Don't miss the somewhat odd TI-40.

The calculator was replaced 1985 with the TI-35 II

This calculator was manufactured at least till week 32 in 1984.
