> IBM’s Boca Raton group understood the momentum behind CP/M as an open standard, and so they commissioned Digital Research to develop a version, called CP/M-86. Later in the process, however, Microsoft came through with the MS-DOS operating system, about which much has already been written. As I understand it, 86-DOS/SDOS was basically an x86 clone of CP/M, and CP/M-80 source programs can even be automatically translated and then reassembled to run on DOS[1] or CP/M-86[2].
