+	11/70 CPU DIAGNOSTIC PART 1
+
+	ABSTRACT:
+
+		This diagnostic is the second part of the 11/70 CPU, it tests advanced
+		instructions and miscellaneous logic.
+
+	OPERATING PROCEDURES:
+	        Set the switch register by <CONTROL P> (RD console)
+	    CON = xxxxxxWZ
+	        (W = deposit xxxxxx into console switch register)
+			(R = read and type console switch settings)
+			(Z = switch console terminal back to program)
+
+	    .R EKBBF0
+
+	SWITCH SETTINGS
+	    SW15 = 1 halt on error
+	    SW14 = 1 loop on test
+	    SW13 = 1 inhibit error typeouts
+	    SW12 = 1 inhibit T-bit trapping
+	    SW11 = 1 inhibit iterations
+	    SW10 = 1 ring bell on error
+	    SW09 = 1 loop on error
+	    SW08 = 1 loop on test in SWR <07:00>
+	    SW07 = 1 not used
+	    SW06 = 1 skip bus request 6 test
+	    SW05 = 1 skip bus request 5 test
+	    SW04 = 1 skip bus request 4 test
+	    SW02 = 1 test selector (with switch 8)
+	    SW01 = 1 test selector (with switch 8)
+	    SW00 = 1 skip operator intervention testing
