The development of DOS had nothing to do with UNIX. DOS was originally the Quick and Dirty OS (QDOS) and was developed by Seattle Computer Products to run on microcomputers. A tiny company called Microsoft bought QDOS in 1981 so they could meet their commitment to IBM to develop an operating system for the IBM PC. By this time, UNIX was a full-fledged operating system, developed in the 1960s at Bell Labs to run on minicomputers. DOS was not based on UNIX and didn't resemble UNIX at all. It resembled CP/M if anything. It didn't even have a hierarchical file system. It wasn't multitasking and still isn't, unless you count TSRs. It didn't support networking. Memory management was a joke. Comparing DOS to UNIX is really low. ;-) Priscilla > > The multi-tasking & multi-threaded functions were > > dropped because there > > weren't enough bits in the registers for the Intel > > 8088.
