The No. 9 Telegraph Testboard[note 1] is a telegraph and Teletype testboard originally installed on the 7th floor of the Pacific Telephone and Telegraph office on 1200 Third Avenue, Seattle in the 1930s. It was used to test and diagnose issues with essentially all teletype traffic in the area: weather stations, newspapers, trucking outfits, air force, navy, FCC, etc. until 1962. The testboard was then replaced by the No. 2 Telegraph Serviceboard (now located at the end of the Teletype area in the museum) and moved to Centralia. It was in service there until the museum acquired it in 1988.
In the museum this testboard is used to connect several Teletypes to each other or to our in-house services like the news. The news service is provided by Aidan's Box Of TTY Magic.
