The Orion was a series of 32-bit super-minicomputers designed and produced in the 1980s by High Level Hardware Limited (HLH), a company based in Oxford, UK. The company produced four versions of the machine: * The original Orion, sometimes referred to as the "Microcodeable Orion". * The Orion 1/05, in which the microcodeable CPU was replaced with the much faster Fairchild Clipper RISC C-100 processor providing approximately 5.5 MIPS of integer performance and 1 Mflop of double precision floating point performance. * The Orion 1/07 which offered approximately 33% greater performance over the 1/05 (7.3 MIPS and 1.33 Mflops). * The Orion 1/10 based on a later generation C-300 Clipper from the Advanced Processor Division at Intergraph Corporation that required extensive cooling. The Orion 1/10 offered a further 30% improvement for integer and single precision floating point operations and over 150% improvement for double precision floating point (10 MIPS and 3 Mflops). All four machines employed the same I/O sub-system. == Background == High Level Hardware was an independent British company formed in early 1982 by David G. Small and Timothy B. Robinson. David Small was previously a founder shareholder and director of Oxford-based Research Machines Limited. Both partners were previously senior members of Research Machine's Special Projects Group. In 1984, as a result of that research, High Level Hardware launched the Orion, a high performance, microcodeable, UNIX superminicomputer targeted particularly at scientific applications such as mathematical modeling, artificial intelligence and symbolic algebra. In April 1987 High Level Hardware introduced a series of Orions based upon the Fairchild Clipper processor but abandoned the hardware market in late 1989 to concentrate on high-end Apple Macintosh sales. 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「HLH Orion」の詳細全文を読む スポンサード リンク
