CMS:No. 2 Telegraph Serviceboard

The No. 2 Telegraph Serviceboard is a serviceboard originally installed on the 7th floor of 1200 Third Avenue from 1962 to 1988. It replaced the No. 9 Testboard which is also in the museum. The No. 2 was an upgrade over the No. 9 largely due to its increased capacity. Most of the technology is the same.

The museum has racks of equipment needed to make the No. 2 operational, but wires need to be run between the racks in the middle of the Teletype collection to the No. 2 at the end and attached in various places, which will involve a considerable amount of effort. The rack equipment is a donation from the Sea-Tac Airport.

The museum's No. 2 was originally labeled "2B electronic hub" which referred to this board pertaining to hub B in the telegraph switching setup.
