Target of this article is to understand some signals of Playstation 2.

In order to develop software for the devices connected to the PC, we should have enough knowledge of computer. The hardware platforms of different ages might vary in interfaces. In a Pentium class x86 PC, the regular interfaces are following: IDE, PCI, AGP, ISA, PCMCIA/PC Card Express, RS232, Parallel port, VGA (maybe you do not think it can be an interface, but you are wrong about it.) and DVI/HDMI, Ethernet, IEEE1394, IrDA, Bluetooth, WiFi and USB.

Skimming the latest Maxim Design Guide, interfaces section, I run into this title: "Add USB to Anything".
