The first transatlantic TDM (Time Division Multiplexer) is then installed by Ultronic and Reuters engineers so that the London master can be fed without renting another transatlantic circuit.This avoids clients having to interrogate the New Jersey master over individual transatlantic lines. As described in John Ransom’s article on Stockmaster, matching the master computer in New Jersey, a slave is installed in London.Reuters now moves into computerised price reporting and the technical development function starts under Glen Renfrew. It relies on the rapid movement of market information to overcome data loss. It is a broadcast and display system with the data stored on large magnetic drums and retrieved on “hardware only” Stockmaster terminals. These in turn are connected to client premises who obtain information by pressing keys on a small desktop unit similar to an adding machine with an electronic display. In the basic Ultronic system, design ticker tapes from stock exchanges and other markets feed into a master computer which feeds into slave memory computers. As well documented elsewhere, the agreement negotiated largely by general manager Michael Nelson gives Reuters exclusive rights to the Ultronic quotation and display systems and technology outside North America. Ultronics is taken over by General Telephone and Electronics - Telnet (GTEIS) which is later taken over by ADP.
