All switches down, turn on machine (set to 000 000) RUN/PROC/BUS/CONSOLE lights come one, all other lights off hit LOAD ADDR address light 16 comes on, RUN/PROC/BUS/CONSOLE lights stay on. If I hit START light 16 turns off. If I try again, to load an address, the address I selected appears, but so does light 16. I believe I have seen the explanation for this symptom somewhere, but reading the 11/40 CPU manual and handbook and I could not find the explanation. Does anyone know what this means? I have been booting directly into the console, lately the system has no problem loading and running from the console. Perhaps this huge missed issue is the root of the problem I have been having get much else done. Bill
