+*   = with 505-6508 chassis; 100K grounding resistor used
+**  = use with external +5v switching power supply
+@@  = install for Kontron compatible Reset operation:
+DIN
+-pin  N8VEM legacy            Kontron compatible
+C-31    output from CPU         input to CPU board
+        peripheral reset
+C-26    not used                output from CPU board
+                            peripheral reset
+If you are not sure, use N8VEM legacy; i.e., don't stuff the switch or 2-pin connector.
