'''PC Open Architecture Developers' Group''' ('''OADG''', Japanese: {{lang|ja|PCオープン・アーキテクチャー推進協議会}}) is a consortium of the major Japanese personal computer manufacturers. Sponsored by [[IBM]] during the 1990s, it successfully guided Japan's [[personal computer]] manufacturing companies at that time into standardising to an [[IBM PC]]-compatible and [[open architecture]].

==History==

Before the advent of the [[IBM PC]] in 1981 in the United States, there were many different varieties and designs of personal computer. Examples from that era include the Tandy [[RadioShack]] and [[Commodore International|Commodore]]. These machines were each based upon a different computer architecture and the software programs that ran on them were compatible only with the machine they had been designed for. In Japan, except for the [[MSX]], this situation continued well into the early 1990s, because eachthree of Japan's major electronics manufacturers (NEC, Sharp and Fujitsu) had also designed itstheir own unique personal computercomputers; although [[NEC]] with its [[NEC 9801PC-98]] was at that time the most successful.{{Attribution<ref needed|datename=September 2010}}"Boyd_1997"/>

The American computer manufacturer [[IBM]] had entered the Japanese market with its own [[IBM 5550]] computer. Japanese-language-capable computers at the time, however, had special requirements in terms of processor capability and screen size, and IBM's [[IBM JX|JX]] project, emphasizing compatibility with the IBM PC, enjoyed limited success. The whole situation was felt by many to be hindering the healthy growth of the Japanese computer industry, particularly since domestic and overseas software vendors had to develop, test and support many different software programs to run on the many different kinds of personal computers sold in Japan.

IBM developed the operating software [[DOS/V]] in Japan, and licensed it to other Japanese PC manufacturers. To promote the IBM PC architecture on which DOS/V worked, IBM sponsored a consortium which was named the PC Open Architecture Developers' Group (OADG) in 1991 and made public its internal architecture and interfaces.<ref name="Myers_1995"/> At the height of this enterprise, the consortium included amongst its members the major Japanese PC manufactures, such as [[Toshiba]] and [[Hitachi]], and overseas manufacturers such as [[Acer Inc.|Acer]] of [[Taiwan]] and [[Dell]] of the United States. Together, they not only strove to develop a unified architecture, but also produced a number of DOS/V-compatible application software programs and participated in the major computer shows. By the time [[Microsoft]]'s computer operating system [[Windows 95]] had arrived in 1995, the IBM PC architecture, using DOS/V, was already a predominant force in Japan.
