Aurora TB607
There's a prolific number of scientific programmable calculators based on the Sharp LI3301A. To date, I counted at least forteen different models; the Aurora TB607 is one of them.
A pleasant multifunction scientific programmable, the TB607 is a good everyday engineering tool. Unfortunately, the programming model leaves a lot to be desired. The programming model is needlessly limited, making it difficult or impossible to implement more complex algorithms. One example is the Gamma function; my favorite programming example cannot be shoehorned into this calculator's limited program space. Instead, I have to contend myself with a less accurate implementation using Stirling's formula:
x-M 1 M+ ÷ RM ÷ 1 2 + 1 = × RM yx RM ÷ RM ex × ( 2 × π ÷ RM ) √ =
