The TI-37 Galaxy Solar added a usable display to the TI-35 Galaxy Solar. Instead of 5 digits for the mantissa you could now use 10 digits. Funny thing: The precision of calculations is worser than expected! The same calculator chip was used in the TI-36 Solar.

Difficult to understand is the reason why the same calculator was sold in Europe with the TI-52 Solar name plate. 

We discovered three "calculator pairs" in the Galaxy series:

US-Market

European-Market

TI-35 Galaxy TI-30 Galaxy
TI-35 Galaxy Solar TI-30 Galaxy Solar
TI-37 Galaxy Solar TI-52 Solar

In 1986 the design style of the TI-37 Galaxy Solar was slightly changed. View the "green" calculator here.

The TI-37 GALAXY SOLAR is featured in the Texas Instruments Incorporated bulletin CL-884 dated 1986.
