Abstract
A read only memory character generator system for generating dot print characters of a given font within a nine-column-by-nine-row dot matrix comprising a read only memory having a storage capacity of one byte per row of memory, the memory having a first memory means, a second memory means and a third memory means with the first memory means having nine memory row locations of memory storage devices for each character of the font to be printed, the memory storage devices at each successive row for each character being burned in pursuant to the dot matrix pattern for successive columns of dots of not more than eight rows for that given column of that given character, the second memory means having one memory row location of memory storage devices for each character of the font to be printed with the storage devices at each location being burned in pursuant to the dot matrix pattern of the remaining columns of the ninth row dot matrix pattern for not more than six columns of dots for the ninth row of one of said characters and a binary code representation for the dot matrix pattern for that particular character, and said third memory means having one memory row location of memory sto…
