The
construction and appearance of the original TI-68 - introduced
1989 - was changed in 1991 to reduce manufacturing costs and enhance durability.
Most
obvious change is the plastic bezel around the display instead the former metal
bezel.
Dismantling
the second generation of the TI-68 reveals no big surprises, the printed circuit
board (PCB) was slightly revised but the Toshiba T9948A single-chip calculator
circuit is still in use.
Another four years later part of the production
of the TI-68 was shifted to Malaysia and later to China, compare the differences here.
Compare
this TI-68 of the second series with the EC-4044 sold by Radio
Shack.
Missing your TI-68? Missing your TI-68? Think about the TI-30X Pro MultiView introduced in 2010 and its twin TI-36X Pro.
