Pinwheel is a Home & Education software developed by Jaap Lameris. After our trial and test, the software is proved to be official, secure and free. Here is the official description for Pinwheel:

This type of calculators were designed about 1850 and were in use until 1970.Electronic calculators already existed at this time, but they were very expensive.

The principle consists of a cilinder with 1..9 extendable pins per digit position.During a revolution of the cilinder, an extended pin advances a gearwheel,incrementing or decrementing the digit, depending on the direction of the rotation.

The program has in-line documentation with examples of various calculations.

Calculations can be performed in STEP mode, showing elementary steps
such as carry propagation.
