A complete 9020E was made up of three or four Model 65s, three Model 50s, storage units, and peripheral adapters for things like displays and incoming radar data These were replaced by 3083s (might have been 3081s). They still existed into this decade and IBM supplied the LIC source to the FAA so they could make them Y2K ready. I have been told they were running VM/SP HPO 5 and the FAA also made that software Y2K ready (after all VM ships as mostly source). I thought all of those had finally been retired, but as you all know, old computer systems never seem to die. I know of a customer who still has MP2000s running OS/390 1.4 with loads of Series 1 machines!
