Abstract

A microprogramming technique is described that is useful in a computer system, such as an IBM Series/l system having random-access memory (RAM) and a wire matrix printer or similar device. Potentially more bytes of RAM are made available for microcode patches and wire image loads. Storage allocations of RAM and various conditions 1-4 following commands received from the central processing unit (CPU) are illustrated in the drawing.
