The SP-1 (Stored Program 1) was the name of a computerized telephone exchange (a so-called switching office) manufactured by Northern Electric (now Nortel Networks beginning in 1972) in Canada. It was introduced around 1967. In reality, this machine was nothing more than a previous generation crossbar switch except that a custom CPU was now operating the mini-bars instead of an electro-mechanical computer known as a marker. Experience with this product gave them the skills to design and build Digital_Multiplex_System.
