ABSTRACT:
A circuit (FIG. 2), for use with a basic display system (FIG. 1), increases by an integral factor M the number (X) of character pixels per display line without changing the rates of clock pulse trains (S.sub.x (f.sub.x), S.sub.1 (f.sub.1)) provided by a timing system (114, 116) resident in the basic system. The circuit increases by the factor M both: (a) the rate at which N-bit words are retrieved serially from the basic system's memory means and (b) the rate at which bits of those of the words, whose bits represent pixels of characters within a scan line, are converted into a stream of MX bits. In one embodiment, M equals 2.
