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.
