Dialing computer

The dialing computer is a Tau'ri-designed device used in Stargate Command in order to dial Stargate addresses. Catherine Langford started the dialing computer project in 1982 and it was improved by Samantha Carter since 1993. This is the Earth version of the Dial Home Device.

Overview
The dialing computer consists in three super-computers (in 1997) located in the Stargate Command control room. To access it, a special keyboard has been conceived to enter Stargate addresses. This keyboard has pads shaped with the Stargate glyphs. Different screens are used to follow the dialing sequence, the Stargate's state, and so on (SG1: ).

History
In 1982, with the development of Project Giza, Catherine Langford leaded a scientific team who started to build a computing system capable of using the Stargate, known at this time as "Doorway to Heaven". This system used three super-computers. In 1993, Langford hired Captain Samantha Carter, theoretical astrophysicist, who improved the dialing computer. According to Carter, this system was "MacGyvered". This system had at first only one designated address stored; the Stargate address found on the Giza cartouche (, SG1: ).
