Calculators with C?

[sat1410]

The PC-G850 versions are much more commonly seen on Japan-based auction sites, and at lower prices. It seems that many were used in school as take-home tools in the '90s and early '00s, much like graphing calculators in the US at the time. The G850 even has a programming interface so that it can be used to program PIC micros--pretty neat stuff. Unfortunately documentation seems to only be in Japanese, because Sharp had withdrawn those types of devices from the international market by the time the G850 was released.
