Book Description
The 120-cell Punched-card Modifiable Logic Array is a repetitive eight-neighbor array of identical NAND gates that can be organized into different data processing subsystems. The signal interconnections between gates are controlled through punched-card operation; any subset of eight-neighbor connections can be made. This versatile and flexible logic array was fabricated for evaluating and verifying cellular logic concepts that appear to have utility for multipurpose or multifunctional arrays. Such arrays could be used in Air Force signal or data processing systems to enhance their flexibility. The array is described, the mode of interconnection control is outlined, and an example of the implementation of a ring oscillator and binary counter chain is presented. (Author).
