About 2 years after introduction of the original TI-307 its design was slightly changed, please look at the coloring scheme.

The next credit card sized calculator was the TI-307+, neither its design nor its quality is exciting.

Don't miss the Casio FIML CARD SL-800, a real credit card sized calculator with a thickness of only 0.030".



The TI-307 is featured in the Texas Instruments Incorporated sales catalog CL-1233 dated 1994.
