The TI-30 SOLAR seems to be identical to the TI-30 Challenger. If you explore the calculator from inside you'll notice the electronics of the earlier TI-30 SLR.

Within one year after its introduction the design of the TI-30 SOLAR was slightly changed.

A more sophisticated calculator was introduced with the TI-31 SOLAR, TI-30 SLR+ and TI-35 SLR.

Recently we received from a former Texas Instruments employee a very early TI-30 SOLAR without any date code.
