the original TI-1000 introduced in June 1977 sports a
golden trim around the keyboard, changed Texas Instruments the design in Summer
1978 to a silver-gray finish.
Dismantling both generations of the TI-1000 reveals a surprise! The earlier model uses a layout similar to 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 TI-1000 on the right was assembled two years later.
A minor difference could be recognized even with the single-chip calculator circuits used in the TI-1000. Some early calculators use a TMC1991 chip, the featured TI-1000 is centered around a TMC1992.
Calculators with different nameplates were sold from Western Auto as Citation.
The technology of the early TI-1000 was chosen for the Little Professor (1978), too.
