This one of several schematics that make up the control logic. This schematic was generated automatically by logic synthesis, driven by the logic spec generated from the microcode, by the microcode compiler. Together with the 6 bit state register this logic makes up control state machine that causes the OSU8 microprocessor to execture code.
