IBM Displaywriter System


The IBM Displaywriter System 6580 was a dedicated microcomputer-based dedicated word processor that IBM's Office Products Division introduced in June 1980.
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" 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 basic word-processing software was Textpack E, with simple mail merge; Textpack 2 added support for double-sided disks, networking, spellchecking, and print spooling; Textpack 4 added automatic hyphenation, columns, and more sophisticated merging; and Textpack 6 added automatic footnoting and outlining. Other options included multilingual dictionaries, graphics, and reports.
The Displaywriter's features were comparable to other word processors 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 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 included:
Because of Displaywriter's popularity, IBM later produced DisplayWrite software for the IBM Personal Computer, with a similar user interface and equivalent to Textpack 4.
