16066285?       IOR - Input/Output With RAM



16072449?         TIO - Timing Input/Output Device Performs timing functions
                                        allowing micro greater efficiency.

16056597?           IOD - I think this is an obsolete part number for
                                         Input/Output Device.  It also helps
the
                                        micro. in efficiency
