Instead
of the earlier golded trim around the keyboard this model sports a silver-gray finsih.
The
main difference between the two TI-1000's is the internal construction. The
earlier model uses a layout like the TI-30,
the later model looks inside like a TI-50.
The picture shows on the left a TI-1000 manufactured in 1977, the right
model was assembled two years later.
Please compare yourself with the TI-1000 (gold).
Calculators with different nameplates were sold from Western Auto as Citation.
The technology of the early TI-1000 was choosen for the Little Professor (1978), too.
