The I/O chip manages :

• A KEYBOARD PORT (compatible PS2),
• A MOUSE PORT (compatible PS2),
• A RS-232C SERIAL PORT,
• A CENTRONICS PORT,
• A FLOPPY PORT (compatible PC),
• A IDE PORT.

This part of the chip manages the link between µcomputer and a Keyboard and/or Mouse compatible PS2.
The OPENCORES Projects is nice because we found a PS2 controller whose will help us to design our PS2 controller.
