NASA PURCHASED EAI 31R 131R AND 231R COMPUTERS FOR THEIR SIMULATIONS WHICH WOULD EXPLAIN WHY THESE COMPONENTS APPEAR TO BE FROM MORE THAN ONE EAI MODEL
THE FIRST PHOTO IS OF THE X-15 FLIGHT SIMULATOR COMPUTER (EAI 231R) WITH THE POT PADDERS AND 26-20D CONTROL PANEL OUTLINED
THE SECOND PHOTO IS OF THE SIMULATION COMPUTERS FROM 1959 (EAI 31R ON THE LEFT / EAI 131R ON THE RIGHT) WITH THE 26-20D CONTROL PANEL AND SET OF ATTENUATOR PANELS OUTLINED
