In 1996 Texas Instruments changes the design of the scientific calculators to a smoother design. The family covers:

Instead the internal construction known from all other members of its family it makes use of two printed circuit boards (PCB's). The larger of the two PCB's holds just the keyboard and is screwed down instead the usual heat stakes.

The BA-35 Solar does:

Preprogrammed financial and accounting functions, including time-value-of-money and compound interest calculations 
Capability for recalling time-value-of-money values as well as annuity due operations 
Amortization balance and payment-to-interest calculations
Annual Percentage Rate (APR) to Effective Rate (EFF) interest conversions
One-variable statistics with frequencies. Calculates mean, sample standard deviation, and population standard deviation.
Cost-sell-margin and mark-up calculations
