#WORD PROCESSING LOGO SERIES#

The CPT 8000 was the company's first microcomputer product, exhibited in spring of 1976. That phosphor subsequently became a standard in the word processing industry and elsewhere. This screen introduced the fast white phosphor P104 in 1976, which was intended to allow rapid scrolling without blurring. CPT screen: Closeup photograph of the CPT 8000-series display screen.

Microprocessor based CPT 8000 series įigure 5. The CPT Communicator was an add-on to the CPT 4200 that allowed data to be transferred from one text-editing machine to another, or between a text-editing machine and a remote computer, via phone lines. Thus a document was edited by reading back those parts of the text to be retained and skipping those parts to be discarded, with new typing added from the Selectric's keyboard. The Selectric's keyboard was active for any new typing, which would appear on the paper and transferred to the output tape. Alternatively, pressing 'skip' moved past the corresponding amount of text on the input tape without sending it to the typewriter or to the output tape. Line boundaries (aka printer margins) recorded on the input tape were ignored or retained depending on whether or not the 'adjust' key had been selected. The keyboard of the CPT 4200 had action keys for 'skip', 'read' and 'stop', mode keys for 'word', 'line', 'paragraph,' and 'page.' Pressing 'read' transferred a word, line, paragraph, or page (depending on which mode key had been selected) from the input tape to both the typewriter and the output tape. That output cassette could later be used as an input cassette, where it would be played back to the typewriter along with new keystrokes to accomplish text editing. Keystrokes entered on the typewriter appeared on the paper as they were recorded on the output cassette, which formed a magnetic replica of the characters printed on the page. The CPT 4200 was a dual-cassette-tape unit with a small built-in keyboard that controlled a modified IBM Selectric typewriter. Selected products Cassette based įigure 3. CPT ultimately ceased major manufacturing late in the 20th century. Corporate revenues grew to approximately a quarter-billion dollars per year in the mid-1980s, then declined with the proliferation of personal computers.

ĬPT Corporation was fifth in size among Minnesota-based top high-tech companies, after 3M, Honeywell, Control Data, and Medtronic. Major competition was IBM, Wang, Lanier, Xerox, and other word processing vendors. The CPT logo-originally three letters chosen to sound well together-began to be taken as an acronym for 'cassette powered typewriting,' and subsequently for 'computer processed text,' and numerous other variants.

Subsequent products included (1) variants on the 8000 series (2) the CPT 6000 series, which had a lower capacity, smaller screen, and was less expensive (3) the CPT 9000 series, which had a larger capacity and could run IBM personal computer software (4) the CPT Phoenix series, which had a graphical capabilities (5) CPT PT, a software-only reduced version that ran on IBM personal computers and clones and (6) other related products. The CPT 4200 was followed in 1976 by the CPT VM (Visual Memory), a partial-page display-screen dual- cassette-tape unit, and shortly thereafter by the CPT 8000, a full-page display dual- diskette desktop microcomputer that drove stand-alone daisy wheel printers.

CPT first designed, manufactured, and marketed the CPT 4200, a dual-cassette-tape machine that controlled a modified IBM Selectric typewriter to support text editing and word processing. CPT Corporation was founded in 1971 by Dean Scheff in Minneapolis, Minnesota, with co-founders James Wienhold and Richard Eichhorn.
