The HP-40G is an algebraic entry only graphing calculator from HP. Based on the HP-38G design, numerous firmware improvements and the inclusion of a CAS made this a very capable math platform. The HP39g and the HP 40g were both released during the year 2000. They are made on the same hardware platform with 1MB of ROM, 256KB of RAM and have 51 keys. The physical difference between the HP39g and the HP 40g is the IR port – 40g does not have IR port.

This calculator is also having the MetaKernel build in and the picture I did pixel by pixel on 20th march 1998 signed “CW” in the bottom left corner when you cold start it (ON-C no data loss, just a software reset). This work with any HP50g including emulators since the image is in the rom.

The HP40g has the same mathematical capabilities as the HP 49.
