editEh? Who's going to find it under this name? The article belongs under its previous (parenthesized) name, or better, SP1 switch analogous to Panel Switch, 5ESS Switch and others. Jim.henderson 15:41, 25 November 2006 (UTC)
Date of introduction
editThe "SP-1 Technical Bulletin" PDF linked at the end of the article shows a date of February 1970. I'd assume that implies an introduction date before the 1971 date mentioned in the article... 198.84.238.55 (talk) 19:19, 28 August 2018 (UTC)
