Compared with the original design of the BA-20 introduced in 1986 this later model lacks the switch to select between battery and solar cells operation.
The third generation of the BA-20 introduced in 1998 omitted the integrated clock.
In Europe a very similar calculator was sold as TI-620.
Don't miss the rare TI-10 Profit Guide combining similiar functions in a much smaller housing.
