86-DOS was created because sales of the Seattle Computer Products 8086 computer kit, demonstrated in June 1979 and shipped in November, were languishing due to the absence of an operating system.
Prodaja računalnog pribora 8086 računalne tvrtke Seattle Computer Products (SCP), koji je bio demonstriran tržištu lipnja 1979., a dostavljen u studenome iste godine, bila je malaksavala zbog toga što taj pribor nije imao operacijski sustav.
