The Executive famously won a Design Council Award for Electronics in 1973 and even went on show at the Museum of Modern Art in New York. Original components: calculator white outer box plush display box operating instruction book brief instruction card leather slip case The usual colouring of the Sinclair Executive Memory has been a white case with black keyboard. Obviously some had the same all black colouring of the original Sinclair Executive.
