The 8086 16-bit processor belongs to Intel and was used to create the 86-DOS .
In April 1980 SCP assigned 24-year-old Tim Paterson to develop a substitute for CP/M-86.Paterson modelled 86-DOS after CP/M-80 's architecture and interfaces , but adapted to meet the requirements of Intel 's 8086 16-bit processor , in order to achieve easy ( and partially automated ) source-level translatability of the large pool of already existing 8-bit CP/M programs .
