What is it?

fxIP is a port of uIP 1.0 to Casio fx-9750/fx-9860 calculators.
It requires calculators with a SuperH SH4a CPU, needs quite a bit of SRAM.

fxIP connects to IP networks via SLIP encapsulation over the 3-pin 2.5mm 5V serial port/UART.

Webserver

fxIP was used to serve a demo page to several thousands of visitors. The project was featured on Golem and Hacker News and actually survived the flood of incoming traffic (with considerable slowdown, of course).
