OS/2 1.x was used as the basis for Citrix Multiuser 1.x was heavily criticized for its poor backwards compatibility, heavier system requirements, design decisions made in order to support 286s instead of just 386s, poor hardware compatibility, and lack of third party driver support.

OS/2 version 1.3 was almost identical to OS/2 1.2 as far as the feature set was concerned but contained a number of performance optimizations and some usability enhancements.

OS/2 is a proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, [2] intended as a replacement for DOS. The first version was released in 1987.

Run DOS, Windows, OS/2 and other vintage PC applications in a web browser on your desktop computer, iPhone, or iPad. An assortment of microcomputers, minicomputers, terminals, programmable calculators, and arcade machines are also available, along with an archive of historical software and documentation.

OS/2 1.2 and 1.3 were developed at a time when the relationship between IBM and Microsoft was becoming severely strained. In late 1988, Microsoft started working on NT, initially developed as NT OS/2 (also known as as “Portable OS/2” on the IBM-Microsoft product roadmap) and ultimately released as Windows NT.

OS/2 1.3 SE was released on November 30th, 1990. This version of IBM OS/2 provided the following enhancements: Increased performance in memory-constrained environments while reducing the minimum memory requirement from 3.5 MB to 3.0 MB.

OS/2 1.3 is said to be more stable then OS/2 1.2, and faster. Â I couldn’t tell the difference, I’m sure being under emulation would be one of the reasons, the other being on a significantly faster machine. Â Nobody could imagine Ghz CPUs in 1987.

OS/2 1.x was a 16-bit OS designed to run on the 80286. OS/2 Version 1.3 was released in 1991 and it was at this time that Microsoft and IBM split up and went their own directions with the OS.

OS/2 1.3是第一个全部由IBM独立负责完成的产品，除了原先的程序码之外，所有新添加的功能都是IBM 自行开发 的。 1.3版比先前的版本执行速度快，程序本身也较小，安装、配置比以前也容易多了，而且加入了Adobe Type I向量缩放字形，支持的 屏幕分辨率 提高到1024×768。 在功能上，IBM也改进了置换文件的演算法，并加入硬盘延迟写入等等。 OS/2 2.0是第一套在PC上运行的真正 多任务操作系统。 1992年，OS/2 2.0正式发表，IBM很自豪地标榜这一版OS/2为“a better …
