Relationship To Similar Equipment

Differences from cpu-136/a: a; outputs not used in cpu-136/a have been deleted. One test connector has been deleted. Memory and hardware growth are increased. B; new data word is transmitted on the mux bus for aircraft maintenance fault code reporting/fault isolation enhancements. C; reliability has been increased. D; air data computer will be maintained at 2 levels in lieu of 3. E; new air data computer can be substituted for cpu-136/a but not vice versa. This is required to prevent demodification of updated aircraft that will not have i-level air data support required for cpu-136/a.
