The present invention provides a retractable wheel system for snowmobile skis. The retractable wheel system of the present invention may be installed on a snowmobile ski without affecting its structural integrity by installing the system on the reinforced portion of the snowmobile ski. When a user circulates in a path with little or no snow, the retractable wheel system is positioned in the extended configuration by the user and the system will automatically return to the retracted configuration when the user returns in a snowy zone. This is realized by using a pre-tensioned spring that will reposition the wheel in the retracted configuration. The spring transmits a rotational movement to the member on which the wheel is fixed.

An interface device (102) and corresponding method for coupling a peripheral controller (117) to a host computer (100), the interface device including an emulated universal asynchronous receiver transmitter (UART) (113) for the host computer. The interface device further includes a plurality of registers (203), preferably a control (215), status (227), and data register, such as a multi-register data buffer (401), corresponding to the registers of a UART, a host computer port (112), preferably compatible with a PCMCIA standard, that includes an address map for the plurality of registers (203), a peripheral controller port (114) providing an address mapped parallel interface to the plurality of registers (203), and control logic (207) for providing status signals, including UART status signals, to the host computer port and to the peripheral controller port. The interface device may further include a pacing circuit (303) for substantially emulating, preferably dependent on a baud rate of the data information, the timing limitations of the UART.
