The computers were used at École Polytechnique Fédérale de Lausanne and in Swiss schools. The names derives from SMArt KeYboard, reflecting the form factor that contained a compact motherboard which fit within the same housing as the keyboard.

The VT50 is a CRT-based computer terminal that was introduced by Digital Equipment Corporation (DEC) in July 1974. It provided a display with 12 rows and 80 columns of upper-case text, and used an expanded set of control characters and forward-only scrolling based on the earlier VT05. DEC documentation of the era refers to the terminals as the DECscope, a name that was otherwise almost never seen.

The MCM/70 is a pioneering microcomputer first built in 1973 in Toronto, Ontario, Canada, and released the next year. This makes it one of the first microcomputers in the world, the second to be shipped in completed form, and the first portable computer. The MCM/70 was the product of Micro Computer Machines, one of three related companies set up in Toronto in 1971 by Mers Kutt. It is considered by some historians to be the first usable personal microcomputer system.
