Kaypro Corporation, commonly called Kaypro, was an American home/
personal computermanufacturer of the 1980s. The company was founded by Non-Linear Systemsto develop computers to compete with the then popular Osborne 1portable microcomputer. Kaypro produced a striking line of rugged, portable CP/M-based computers which supplanted its competitor and quickly became one of the top selling personal computer lines of the early 1980s.
While exceptionally loyal to its original consumer base, Kaypro was slow to adapt to the changing computer market and the adoption of
IBM PC compatibletechnology. It faded from the mainstream by the end of the decade and was eventually forced into filing for bankruptcyin 1992.
Kaypro began as Non-Linear Systems, a maker of electronic test equipment, founded, in 1952, by
Andrew Kay, the inventor of the digital voltmeter.
In 1981, Non-Linear Systems began designing a personal computer, called KayComp, that would compete with the popular
Osborne 1transportable microcomputer. In 1982, Non-Linear Systems organized a daughter company named the Kaypro Corporation and rechristened the computer with the same name.
The first product, the Kaypro II, carried the Roman-numeral designation because the most popular microcomputer at the time, other than the
IBM PC, was the Apple II. The Kaypro II was designed to be portable like the Osborne. (When laptop computers became available, the larger machines came to be called "transportable" or "luggable", rather than "portable".) Set in an aluminum case, it weighed 29 pounds (13 kilograms) and was equipped with a Zilog Z80 microprocessor, 64 kibibytesof RAM, and two 5¼-inch double-density floppy-disk drives. It ran on the CP/M operating systemof Digital Research, Inc., and sold for about US$1,795.00.
By mid-1983, Kaypro had dropped the price to $1,595, and was selling more than 10,000 units a month—briefly making it the fifth-largest computer maker in the world. The Kaypro II's market success was due to a number of factors: it had a larger screen than the Osborne; it came bundled with third-party
application software(PerfectWriter and PerfectCalc, later to be replaced by MicroPro's WordStarand CalcStar); and it was supported by a network of trained dealers. The boxy units were so popular that they spawned a network of hobbyist user groups across the United Statesthat provided local support for Kaypro products. Kaypro's success contributed to the eventual failure of the Osborne Computer Corporation.
Kaypro published and subsidized "ProFiles: The Magazine for Kaypro Users", a monthly, 72-page, four-color magazine that went beyond coverage of Kaypro's products to include substantive information on CP/M and
MS-DOS; frequent contributors included Ted Chiang, David Gerrold, Robert J. Sawyer, and Ted Silveira.
Another popular magazine that covered Kaypro computers was "
Micro Cornucopia", published at Bend, Oregon.
Following the success of the Kaypro II, Kaypro moved on to produce a long line of similar computers into the mid 80's. Exceedingly loyal to its original core group of customers, early machines ran on the CP/M operating system. In 1985, Kaypro began producing IBM compatible MS-DOS machines, the Kaypro 16 (transportable, same form factor as the original), the Kaypro PC, Kaypro AT (a 286 machine), the Kaypro 386, and the Kaypro 2000 (a rugged aluminum-body battery-powered laptop with a detachable keyboard). The slow start into the IBM clone market would have serious ramifications.
After several turbulent years, with sales dwindling, Kaypro filed for
Chapter 11bankruptcy in March 1990. Despite restructuring, the company was unable to recover and filed for Chapter 7 bankruptcy in June 1992. In 1995, its remaining assets were sold for $2.7 million.

The Kaypro name briefly re-emerged as an online vendor of PCs in 1999, but was discontinued in 2005 by its parent company [http://www.premiopc.com/ Premio Computers Inc.] due to sluggish sales.

Kaypro founder Andy Kay re-emerged from the final failure of Kaypro with a second company, called
Kay Computers, utilizing a similar sales strategy.
Early in the Kaypro’s life, there was a legal dispute with the owner of the
Bigboardcomputer who charged that the Kaypro II main circuit boardwas an unlicensed copy or clone.
The outer case was constructed of
aluminum. The computer featured a detachable keyboard that covered the screen and disk drives when stowed. The Kaypro ran off regular AC mains power and was not equipped with a battery.
The Kaypro IV and later the Kaypro 4 had two double-sided disks. The Kaypro 4 was released in 1984, usually referred to as Kaypro 4 '84, as opposed to the Kaypro IV released one year earlier and referred to as Kaypro IV '83.
The Kaypro 10 followed the Kaypro II, and featured a 10
megabyte hard driveand a single 5¼" floppy drive.
Kaypro later followed their CP/M machines with
MS-DOS-based computers in the Kaypro 16, Kaypro PC and others, as the IBM PCand its clones gained popularity. Kaypro was late to the market, however, and never gained the kind of prominence in the MS-DOS arena that it had enjoyed with CP/M. Instead, Kaypro watched as a new company Compaq, grabbed its market share with the Compaq Portable, an all-in-one portable computer that was similar to Kaypro's own CP/M portables with the exception that it ran MS-DOS and was nearly 100% IBM compatible. This and other corporate issues helped lead to Kaypro's eventual downfall.
CP/M was the standard
operating systemfor the first generation of Kaypros. The first application softwarethat came with the Kaypro II included a highly unpopular word processor called "Select" that was quickly dropped in favor of an office suite from Perfect Softwarewhich included [http://www.atarimagazines.com/creative/v9n6/55_Perfect_Writer.php PerfectWriter] , PerfectCalc, PerfectFiler, and PerfectSpeller, as well as Kaypro's own compiled S-BASIC (which produced executable .com files). PerfectFiler featured non-relational, flat-file databases suitable for merging a contact list with form letters created in PerfectWriter. PerfectWriter itself was initially just a rebranded Mince and Scribble from Mark of the Unicorn, which was itself a CP/M implementation of the (then) mainframe Emacsand Scribeusing BDS C. Later on MBasic(a variant of Microsoft Basic) and The Word Plus spellchecker were added to the model II suite of software. The Word Plus included a set of utilities that could help solve crossword puzzles or anagrams, insert soft hyphens, alphabetize word lists, and compute word frequencies. Another utility program called Uniform allowed the Kaypro to read disks formated by Osborne, Xerox, or TRS-80computers.
The initial bundled applications were soon replaced by the well-known titles
WordStar, (a word processorwith MailMerge, for personalised mass mailings), the SuperCalc spreadsheet, two versions of the Microsoft BASICinterpreter, Kaypro's S-BASIC, a bytecode-compiled BASIC called C-Basic, and the dBaseII relational databasesystem.
comma-separated values(CSV) file format(better known at the time as CDF or comma delimited format or comma delimited file), data could be moved between these programs quite easily, which enhanced the utility of the package. The manuals assumed no computer background, the programs were straightforward to use, and thus it was possible to find the CEOof a small company or somebody else developing the applications needed in-house.
The Kaypro II and later models also came with some games, including versions of old character-based games from earlier days (for example, "Star Trek"), and a few of which were arcade games re-imagined in
ASCII, including "CatChum" (a Pac-Man-like game) and "Ladder" (a "Donkey Kong"-like game).
All this software if bought separately would have cost more than the entire hardware and software package together. The Kaypro II was a very usable and (at the time) powerful computer for home or office, even though the painted metal case made it look more like a rugged laboratory instrument than an office machine. They enjoyed a reputation for durability.
Later MS-DOS Kaypro computers offered a similar software bundle.
Kaypro by model and year
Kaypro's nomenclature was odd, with the numerical designations for their machines having more to do with the capacity of the drives than the order they were produced. Kaypro also released several different models with the same names, perhaps hoping to capitalize on the name recognition of their older machines. As a result, identifying exactly which model a Kaypro is often requires an inspection of their hardware configuration.
All of the computers listed below are of the portable type unless otherwise noted.
* 1982:"Kaycomp I" - The original Kaypro, was a demonstrator model shown mainly to prospective dealers. It had the same case as future models, but was painted green with two single sided floppy drives that were mounted vertically on opposite sides of the monitor like the Osborne I, its intended competition.
:"Kaypro II" - The first commercially released Kaypro, was an immediate success, dominating over its competition, the Osborne I microcomputer. The Kaypro II had a 9 inch internal monitor instead of the Osborne's tiny 5 inch display, and double sided floppy drives with twice the storage capacity. A redesigned version of the Kaypro II was released in 1984 that allowed block style graphics, and had half-height drives. This version of the Kaypro II had a version of Space Invaders along with the typical ASCII games.
* 1983:"Kaypro IV" - An evolution of the Kaypro II, the Kaypro IV had two DS/DD drives (390 kB) and came with Wordstar in addition to the Perfect Suite of software.
:"Kaypro 10" - The Kaypro 10 was one of the earliest computers to come standard with a
hard drive. It came with a 10 megabyte internal hard drive and a single DS/DD floppy drive. All of the computers produced until then had been green or light grey or grey and blue, but the K10 was dark grey, almost black.
* 1984:"Kaypro 4" - The Kaypro 4 was virtually identical to the IV, but featured half-height drives instead of full height drives, a 4 MHz clock speed and had basic graphics capabilities. It also had an internal 300-baud modem.
:"Kaypro Robie" - The Kaypro Robie was the only CP/M based Kaypro to be non-portable. Designed as a desktop computer, it had the same motherboard as the Kaypro 4. It was also equipped with two 2.6 MB high density floppy drives and a 300 Baud modem. The floppy drives were notorious for failing as they literally scraped the media off of the disk substrate, leaving many customers with drives which they could not read. The Robie was jet black, with the drives mounted above the screen, and the front panel angled upward. The Robie did not sell well, but it did make periodic cameo appearances on the ABC television series "Moonlighting", as the desktop computer used by
Bruce Willis' character David Addison. Due to its black color, the fact that it sat upright and looked like a helmet, and its handle mounted on the top, it was nicknamed "Darth Vader's lunchbox."
* 1985:"Kaypro 2X" - The Kaypro 2X was similar to the Kaypro 4, but it featured a built in 300 baud modem. Kaypro 2X's were often sold in a bundle with an
:"Kaypro "New" 2" - A scaled-down Kaypro 2X for the budget buyer, came with minimal software, and did not feature the internal modem.
:"Kaypro 4+88" - A dual system computer, the 4+88 was equipped with both an 8088 processor and a Z80, and was capable of running both the MS-DOS and CP/M operating systems. It came with 256 KB of RAM for the MS-DOS operating system that could double as a
RAM diskfor CP/M.
:"Kaypro 16" - Very similar in appearance to the Kaypro 10, the Kaypro's 16's main difference was that it had an 8088 processor and 256 KiB of RAM and ran on the MS-DOS operating system instead of CP/M.
:"Kaypro 2000" - Kaypro's first and only laptop, it was an MS-DOS machine that ran on heavy lead-acid batteries. Strikingly similar in basic appearance to a modern laptop, it featured a detachable keyboard, rugged brushed aluminum casing and a pop-up 3.5 inch floppy drive. In what seems to have been a recurring comparison, it has been called "Darth Vader's laptop".
:"Kaypro PC" - Late on the PC market, the Kaypro PC was intended as a competitor to the IBM
PC-XTdesktop machine. Running at a faster clock speed than IBM's machine, it was available with a larger hard drive than that offered by IBM and an extensive software package. It featured the motherboard on a bus card, which, like the Zenith Z-series machines, promised upgradability.
* 1986:"Kaypro 1" - The Kaypro 1 was the last CP/M model Kaypro introduced. In most ways, it was simply a Kaypro 2X with a smaller software package. It is distinctive from earlier Kaypro models because of its vertically oriented disk drives.
:"Kaypro 286i" - A 12 MHz 286 desktop, with a faster clock speed than IBM's machine, a larger hard drive than IBM's configuration and an extensive software package. It featured the motherboard on a bus card, which, like the Zenith Z-series machines, promised upgradability.
:"Kaypro 386" - A 20 MHz 386 desktop, with an extensive software package. It featured the motherboard on a bus card, which, like the Zenith Z-series machines, promised upgradability.
Kaypros in popular media
Science fictionwriter Arthur C. Clarkewrote the script for "2010" on a Kaypro II in 1982, using a modem to transmit the script to his studio contact in California from his home in Sri Lanka.
*The Kaypro Robie made periodic
cameo appearances on the ABC television series "Moonlighting", as the desktop computer used by Bruce Willis' character David Addison. The computer also made a " Miami Vice" cameo.
* In the 2001 film "The Score", a hacker boasts, "Give me a Kaypro 64 and a dialtone and I can do anything." Although the "Kaypro 64" never existed, it nevertheless refers to Kaypro computers. The "64" is possibly a reference to the mass familiarity of the
Commodore 64 home computer; or perhaps it's a reference to the amount of factory-installed RAM in the Kaypro II.
* In the animated TV series "King of the Hill",
Peggy Hilluses a Kaypro to write her musings. It was replaced in the Season 4 episode " Hillennium" by an iMac.
* In the third season of the
Fox televisionshow "Arrested Development", George has taken all the computers to destroy the evidence on the hard drives. Michael Bluth can be seen using an old Kaypro because of this.
The Simpsons, Marge mentions that they got their Kaypro by Nelson dropping it off the freeway overpass.
* In "
I Am Charlotte Simmons" by Tom Wolfe, Charlotte's poor family gives her a Kaypro computer, which they had rebuilt from parts, as a Christmas present.
