Hope this clarifies. The small round CRT left of the controller is a DFTI (Distance from touchdown indicator) . Early version taken off the AR-15 Primary only blips ,usually set gated to the 10 miles of final for the runway in use , you had to have a call from radar to identify the aircraft next on final. The TV screen lower right is the ASMI representation (surface movement indicator) again monochrome only with no labelling.
