The IBM Displaywriter System 6580 was a dedicated microcomputer-based word processing machine that IBM's Office Products Division introduced in 1980.〔 (【引用サイトリンク】title=IBM Displaywriter )〕 The system consisted of a central processing unit, based on the Intel 8086, in a desktop case, a monochrome CRT monitor atop the CPU, a detached keyboard, a detached dual disk drive that used 8-inch floppy disks, and a detached daisy wheel printer. The system booted from an 8-inch floppy disk that stored IBM's internally developed word processing software. The operator stored the "documents" (i.e., data files) on additional diskettes. "A basic system — consisting of a display with a typewriter-like keyboard and a logic unit, a printer and a device to record and read diskettes capable of storing more than 100 pages of average text — cost $7,895 and leased for $275 a month."〔 The Displaywriter's features were comparable to other dedicated word processing machines of its era. The features included mail-merge, with fields designated as a01, a02, a03, etc. Elementary arithmetic could be applied to the fields. The basic IBM Displaywriter was a standalone system. An optional central storage and management unit was available, which permitted multiple Displaywriters to share storage and a printer. UCSD p-System operating system and CP/M-86 were available for the Displaywriter System but were not its regular Operating System. Connections to other IBM systems have been available: * IBM 3278 emulation program to attach to IBM 3274/3276 controllers, IBM 4321/4331, or IBM 4701. * IBM 3277 emulation program to attach to IBM 3271, 3272 or 3274 controllers. * Connection to IBM 8100 systems which use DPCX/DOSF. IBM later produced "DisplayWrite" software for the IBM Personal Computer with a similar user interface to capitalize on the Displaywriter's popularity. ==References== 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「IBM Displaywriter System」の詳細全文を読む スポンサード リンク
