Computer History Museum curator Dag Spicer passed along a question from former CHM curator

processor called M3 which was written by D. M. Ritchie for the AP-3 minicomputer; M3 was

Software Tools, Addison-Wesley, Inc., 1976].
Alex and Dag would like to learn more about this AP-3 minicomputer — can anyone help?
