RISC iX was a Unix operating system designed to run on the Acorn Archimedes. Heavily based on 4.3BSD, it was initially completed in 1988 — a year after Arthur but prior to RISC OS. == Features == * X11 (initially Release 2) with Ardent Window Manager, Tom's Window Manager and Ultrix Window Manager available by default * System V virtual memory extensions, compatible with the "System V Interface Definition" * C Compiler with ANSI C and pcc (Berkeley) compatibility * Sun Network File System version 3.2 * ARM Assembler Later versions upgraded the X11 server to release 4, and was certified to conform to the X/Open Portability Guide 3 Base profile. The native file system implemented a transparent executable file compression mechanism that took advantage of the hardware's 32 KiB page size and sparse files. Additionally, the console featured a two-cursor text copying mechanism inspired by Acorn's own earlier 8-bit range including the BBC Micro. 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「RISC iX」の詳細全文を読む スポンサード リンク
