IBM is seriously challenged in operating system markets and needs a cohesive and consistent software approach, such as SAA, to compete. In the mainframe area, IBM's domination is nearly complete. MVS (multiple vertical system) is IBM's premiere operating system, although VM (virtual memory), developed jointly with MIT, is still around. There is competition in the midrange system market, mainly from DEC. In PC systems, the wars are truly volatile: the MS- and PCDOS standard is evolving to OS-2, which IBM plans to extend. Apple has two systems, Apple II and Macintosh, with Macintosh the wave of the future. UNIX is pushed by a number of workstation vendors. Many believe the real war will be between MSDOS, OS-2 Standard Edition, and IBM's Extended Edition of OS-2.
