HP-Xpander

The HP-Xpander was to be HP's newest graphing calculator, but the project was canceled just months before it was scheduled to go into production. It had both a keyboard and a pen-based interface, measures 162.6 mm by 88.9 mm by 22.9 mm, had a huge grayscale screen, and ran on two rechargeable AA batteries. It had a semi-translucent green cover on a gray case and an expansion slot.

The underlying operating system was Windows CE 3.0. It had 8MB RAM, 16MB ROM, a geometry application, 240x320 display, Hitachi SH3 processor, and e-lessons. One of the obvious omissions in the Xpander was the lack of a computer algebra system.

In 2001 HP's design group in Australia was disbanded. HP decided to release the HP-Xpander software, named the Math Xpander, as a free application that runs on Windows CE based Pocket PC devices. The Math-Xpander software is hosted by Saltire Software Inc..
