The I2C bus has recently appeared on PCs in video capture boards and similar devices, as well as (surprisingly) SDRAM DIMMs (for the on-board serial EEPROM).  The ACCESS.bus is a derivative of the I2C bus which forms the physical layer of the Universal Serial Bus.	 Similary, the SMBus (System Management Bus) also uses I2C as its physical layer. xxh"CS4922")
