OS/2: Microsoft's Ambitious Next-Gen OS

A 1987 Computer Language article detailed Microsoft's then-new OS/2, predicting its potential to dominate Intel 80286/80386 microcomputers for the next decade. Its multitasking, comprehensive API, and hardware extensibility were highlighted as key strengths. OS/2's architecture featured three layers: the kernel and system services, the Windows Presentation Manager (WPM), and the OS/2 LAN Manager. The article focused on the kernel and its system services, covering process management, memory management (including virtual memory), device drivers, file management, and inter-process communication (IPC). OS/2 used preemptive scheduling and time slicing, supported protected and real modes, and offered MS-DOS compatibility. Dynamic linking was a crucial element, enhancing code reuse and future-proofing applications. The article concluded by speculating on OS/2's future enhancements and 80386 support.
