In the early 1970s, word processing then became computer-based (albeit with specialty based computing) with the development of several innovations. Just before the arrival of the Personal Computer (PC), IBM developed the “floppy disk”. Also in the early 1970s word-processing systems with a CRT screen display editing were designed. At this time these stand-alone word processing systems were designed, built and marketed by several pioneering companies. Linolex Systems was founded in 1970 by James Lincoln and Robert Oleksiak. Linolex based its technology on microprocessors, floppy drives and software. It was a computer-based system for application in the word processing businesses and it sold systems through its own sales force. With a base of installed systems in 500 plus customer sites, Linolex Systems sold 3 million units in 1975 — a year before Apple Computer, was first incorporated in 1976. At this time, Lexitron Corporation also produced a series of dedicated word processing microcomputers. Lexitron was the first to use a full size video display screen (CRT) in its models by 1978. Lexitron also used 5-1/4 inch floppy diskettes, which were the standard in the personal computer field. The program disk was inserted in one drive, and the system booted up. The data diskette was then put in the second drive. The operating system and the word processing program were combined in one program.
Another of the early word processing adopters was Vydec, which created in 1973, the first modern text processor, the “Vydec Word Processing System”. It had built-in multiple functions like the ability to share content by diskette and print it. The Vydec Word Processing System sold for $12,000 at the time, (about $60,000 adjusted for inflation). The Redactron Corporation (organized by Evelyn Berezin in 1969) designed and manufactured editing systems, including correcting/editing typewriters, cassette and card units, and eventually a word processor called the Data Secretary. The Burroughs Corporation acquired Redactron in 1976. A CRT-based system by Wang Laboratories became one of the most popular systems of the 1970s and early 1980s. The Wang displayed text on a CRT screen, and incorporated virtually every fundamental characteristic of word processors as we know them today, a true office machine, affordable by organizations such as medium-sized law firms, and easily learned and operated by secretarial staff.
