Abstract: Embodiments of the present invention illustrate various configurations of a channel-to-controller interface. In one embodiment, width of symbols crossing the interface is fixed, as is the clock rate. In other embodiments, the symbol width is variable, and the clock rate is also varied based upon the size of the interface symbol width and the operation of the channel.

Abstract: A calendar having a plate-like support adapted to be mounted in an upright or flat position. The support has a number of first strips having spaced, vertically aligned numerals thereon which indicate certain days of a month. The support has mounting means for removably positioning the strips in generally upright positions so that, when the strips are properly arranged on the support, the numerals on the strips will be in the proper positions to indicate the days of a particular month. A group of second strips with the months of the year printed thereon are used one at a time to indicate a particular month. Mounting portions on the support removably positions each of the second strips on the support. In one embodiment of the calendar, the support has a recess for storing the second strips which are not being used. In the first embodiment, the mounting portions are pegs which extend laterally from the flat front face of the support and are received in holes in the first strips.
