Microport (1985–2002) created the first version of AT&T UNIX System V for the IBM 286 and 386 Personal Computers, as well as IBM's PS/2 systems. Together, these IBM families formed the backbone of what is now known as the Intel x86 architecture. By taking a new (at the time) approach, they were able to dramatically reduce development costs, and consequently, the price charged for UNIX. At the Free Software Foundation (FSF)'s request, Microport donated a complete 386 development system to the Richard Stallman-led group. This was done for the explicit purpose of enabling the FSF to port its GNU C compiler (gcc) and associated utilities, onto the x86 architecture. GCC was, and still is, one of the largest free software projects available, permitting both the BSD and Linux programmers to develop those operating systems in the 1990s. Microport also played a key role in Kevin Mitnick's first arrest, after he broke into the internal computer networks of both Microport and The Santa Cruz Operation. == Historical perspective == Previously, if one wanted the power of UNIX, one was limited to either expensive minicomputers, or the less sophisticated (and still expensive) XENIX or other UNIX derivatives. None of these solutions was intended to make UNIX affordable to the average person, focusing instead on the larger (and more profitable) OEM and VAR commercial deals. Microport's System V implementation was designed for the low-cost market, originally targeting the hobbyist, while capturing the attention of the OEMs and VARs. Unfortunately for the hobbyists, Microport later moved away from the original roots of the individual hobbyist, turning instead towards selling to OEMs and VARs; gradually raising the price of the software until it was no longer easily affordable to the average person (although it was always cheaper than SCO's XENIX). Nonetheless, others saw what Microport had done, and this left the market open for other low-cost UNIX technology to follow, including Linux and BSD for the PC's in the 90's, among others. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Microport」の詳細全文を読む スポンサード リンク
