Abstract: An L-shaped molded plastic panel which is adapted to be joined with three similar L-shaped panels to form the respective side walls of a rectangular tubular housing.

Abstract: A video display device generates a plurality of character rows having a total height of ten lines containing a plurality of characters constructed of a seven dot wide, eight dot high matrix. A read-only memory for the character generator stores eight-bit signals for each character. The ROM receives a signal from a line-within-a-row counter and the least three significant bits of a four-bit character code to output the pertinent eight-bit signal. Seven bits of the signal are provided in parallel to a parallel/serial converter which causes them to be outputted to the video display sequentially as the dot time signal changes. The eighth bit of the code as well as the most significant bit of the character code are provided to a logic circuit which clears the parallel/serial converter during the generation of two of the ten lines of a row.
