"[10] Initial service test models of the Burroughs AN/FST-2 Coordinate Data Transmitting Set were placed with radars at South Truro and West Bath, Maine; followed by Texas Tower#2 (TT2) in the Atlantic Ocean, which provided a "triangular pattern with overlap" radar coverage[11] (TT2 later had a connection from the XD-1 via the GE G/A Data Link Output Subsystem through North Truro Air Force Station.

[23] WWI was connected to the Experimental SAGE Subsector to verify crosstelling (collateral communication) with the ESS DC, and WWI was also used for a Ground-to-Air (G/A) experiment using a transmitter of the GE G/A Data Link Output Subsystem on Prospect Hill, Waltham, MA sending data to simulated airborne equipment at Lexington.

[12] Transmissions from the WWI SAGE Evaluation (WISE) computer system[3] to XD-1 and back were without error by December 1955[3] when operational software specifications were frozen.

)[28] The North Truro P-10 AN/FST-2 was moved to Almaden Air Force Station (M-96)c. 1957-8[27] and on August 7, 1958, control of an airborne BOMARC missile that had malfunctioned transferred from the "Experimental SAGE Sector" to a Westinghouse AN/GPA-35 Ground Environment system[where?]

[30] "To prove out the revised SAGE computer program" for Automatic Targeting and Battery Evaluation and ADDC-AADCP crosstelling, a "SAGE/Missile Master" test was conducted beginning in September 1959 with communications between the ESS XD-1 and Martin AN/FSG-1 Antiaircraft Defense System equipment at Fort Banks[31] planned for the CONAD Joint Control Center at Fort Heath[32]—a "SAGE ATABE Simulation Study" (SASS) was also completed 1959–60 by MITRE Corporation.
