IBM LAN Server is a discontinued network operating system introduced by International Business Machines (IBM) in 1988. LAN Server started as a close cousin of Microsoft's LAN Manager and first shipped in early 1988. It was originally designed to run on top of Operating System/2 (OS/2) Extended Edition. The network client was called IBM LAN Requester and was included with OS/2 EE 1.1 by default. Here the short term LAN Server refers to the IBM OS/2 LAN Server product. There were also LAN Server products for other operating systems, notably AIX—now called Fast Connect—and OS/400.
Zenith Data Systems Corporation (ZDS), was an American computer systems manufacturing company active from 1979 to 1996. It was originally a division of the Zenith Radio Company, after they had purchased the Heath Company and, by extension, their Heathkit line of electronic kits and kit microcomputers, from Schlumberger in October 1979. ZDS originally operated from Heath's own headquarters in St. Joseph, Michigan. By the time Zenith acquired Heathkit, their H8 kit computer already had an installed fanbase of scientific engineers and computing enthusiasts. ZDS' first offerings were merely preassembled versions of existing Heathkit computers, but within a few years, the company began selling bespoke systems, including the Z-100, which was a hybrid Z80- and 8088-based computer capable of running both CP/M and MS-DOS.
The LTE is a line of laptops manufactured by Compaq Computer Corporation, introduced in 1989 and discontinued in 1997. It was the first notebook-sized laptop sold by Compaq and the first commercially successful notebook computer, helping launch the burgeoning industry.
The Satellite Pro is a line of laptop computers designed and manufactured by Dynabook Inc. of Japan, which was formerly Toshiba's computer subsidiary. The Satellite Pro is currently positioned between their consumer E series and their business Tecra series of products.
The LTE Lite was a series of notebook-sized laptops under the LTE line manufactured by Compaq from 1992 to 1994. The first entries in the series were Compaq's first computers after co-founder Rod Canion's ousting and Eckhard Pfeiffer's tenure as the new CEO. The notebooks were co-developed and manufactured by Compaq and Citizen Watch of Japan. They were a hot-seller for Compaq and spanned multiple models, with various processors and liquid-crystal display technologies.
Reply Corporation, often shortened to Reply Corp., was an American computer company based in San Jose, California. Founded in 1988 by Steve Petracca, the company licensed the Micro Channel architecture from IBM for their own computers released in 1989, competing against IBM's PS/2 line. The company later divested from offering complete systems in favor of marketing motherboard upgrades for older PS/2s. Reply enjoyed a close relationship with IBM, owing to many of its founding employees, including Petracca, having worked for IBM. The company was acquired by Radius in 1997.
The Versa was a line of laptop computers sold by the Japanese electronics conglomerate NEC Corporation from 1993 to 2009. It comprised many form factors of laptops, from conventional clamshell notebooks to pen-enabled convertibles featuring detachable displays, before the line was effectively discontinued in 2009 after NEC pulled out of the global market for personal computers.
The ActionNote was a series of laptop computers developed by Epson America in 1993. The series was Epson's answer to the small businesses and home office market for laptops and initially ran alongside their corporate-oriented NB series of laptops. The series was segmented into premium and low-cost offerings and included a subnotebook, the ActionNote 4000. The bulk of the laptops' manufacturing was performed by ASE Technologies of Taiwan, with the exception of the short-lived initial entries into the 700 series, which were produced by Jabil Circuit. The ActionNote received mixed, mostly positive, reception in its lifespan before Epson America silently left the personal computer market in 1996.
Canon Computer Systems, Inc. (CCSI), sometimes shortened to Canon Computer, was an American subsidiary of Canon Inc. formed in 1992 to develop and market the parent company's personal computers and workstations. The subsidiary also assumed the responsibility of marketing Canon's printers and photocopiers, which were formerly sold by other Canon divisions. It went defunct in January 2001.
The Compaq Professional Workstation was a family of workstations produced by Compaq. Introduced in late October 1996, the first entry in the family featured single or dual Pentium Pro processors. Later entries featured Pentium IIs and IIIs; the XP1000 was the only non-x86 based entry, featuring a DEC Alpha processor. Compaq aimed the Professional Workstation at computer-aided design users, software programmers, multimedia designers and financial workers. While workers of those fields primarily ran Unix-based operating systems on workstations at the time, the Compaq Professional Workstation came preinstalled with Windows NT 4.0 Workstation. The line was discontinued in 2002.
DTK Computer is the name for international branches of Datatech Enterprises, a Taiwanese computer manufacturer. Founded in 1981, the company was an early supplier of peripherals for IBM PCs as well as PC compatible motherboards. In the late 1980s, the company switched to developing complete systems under the DTK name as well as serving as an OEM for motherboards and cases, as bought by other small computer companies and systems integrators.
Librex Computer Systems Inc. was a short-lived American subsidiary of the Nippon Steel Corporation that manufactured notebook computers from 1990 to 1992. Librex had roots in Nippon Steel's Electronics and Information Systems Division (EISD) back in Japan, which starting in 1986 had formed joint ventures with several high-profile American computer companies. Librex was Nippon Steel EISD's first venture in the United States; it also set up Nippon Steel Computer PLC in the United Kingdom to sell identical products. The company's notebooks received praise in the technology press, but a fierce price war in the market for laptops in the early 1990s combined with dwindling profit margins compelled Nippon Steel to dissolve Librex in 1993.
Aox Inc. was a privately run American technology corporation founded by Michael and Linda Aronson in 1978. Over the course of its 22-year lifespan, the company chiefly developed software and hardware for IBM's PC and compatibles, for the Personal System/2, and for the Macintosh. In its twilight years, the company designed multimedia and teleconferencing devices and chip designs. Aox was founded after Michael Aronson graduated from Harvard University with a doctorate in physics; he stayed with the company until 2000, when he incorporated EndPoints Inc. and switched to full-time fabless semiconductor design.
Cumulus Corporation was an American computer peripheral and system manufacturer active from 1987 to 1993. Based in Beachwood, Ohio and started by Tecmar founder Martin Alpert, the company set out to exclusively manufacture expansion products for IBM's Personal System/2 (PS/2) family of computers—mainly RAM expansion cards. It later released cross-platform CPU upgrade cards and memory expansion cards for other platforms besides the PS/2. Beginning in 1990, the company began trading as Cumulus Computer Corporation and began releasing complete systems of their own. Initially a success story for the tech industry in Cleveland, a botched stock launch in 1992 proved disastrous for the company's ailing cash flow situation, and in 1993 the company was liquidated amid massive debt to suppliers and lenders.
BusLogic, Inc., was an American computer company active from 1988 to 1996. It specialized in the production of Small Computer System Interface (SCSI) device controller chips and controller expansion cards, becoming a dominant player in that market, behind only Adaptec. In 1996, the company was acquired by Mylex Corporation.
Actix Systems, Inc., was an American graphics adapter manufacturer active from 1990 to 1998 and based in the San Francisco Bay Area. The company was founded by Stephen W. Cheng and initially specialized in a subset of graphics adapters known as GUI accelerators, becoming a major player in the field. Toward the mid-1990s the company began manufacturing more general-purpose adapters under their GraphicsEngine brand.
The LTE Elite was a series of notebook-sized laptops under the LTE line manufactured by Compaq from 1994 to 1996. All laptops in the LTE Elite range sported Intel's i486 processors, from the 40 MHz DX2 to the 75 MHz DX4. The LTE Elite was the first notebook-sized laptop to house the AC adapter inside the case itself, eliminating the need to carry an external power brick. The LTE Elite line was replaced by the LTE 5000 series in 1995. Compaq ceased manufacturing the LTE Elite line in March 1996.
The LTE, LTE/286, and LTE/386s were a series of notebook-sized laptops manufactured by Compaq from 1989 to 1992. The three laptops comprise the first generation of the LTE line, which was Compaq's second attempt at a laptop following the SLT in 1988 and their first attempt at a truly lightweight portable computer. The LTE line proved highly popular—Compaq selling hundreds of thousands of units between the three—and gave way to successive generations of the line, including the LTE Lite, the LTE Elite, and the LTE 5000 series. With its use of industry-standard floppy and hard drive technologies, the LTE was the first commercially successful notebook computer and helped launch the fledgling notebook industry, which had seen earlier attempts fail due to the use of novel but nonstandard data storage.
The Walkabout is a family of notebook-sized laptop computers introduced by Data General in 1989 and discontinued in 1993. The first entry in the line, simply named the Walkabout, was a battery-powered portable terminal capable of emulating multiple protocols; as well, it contains a rudimentary word processor, an autodialer utility for placing phone calls, and a real-time clock display and timer application for setting reminders. The successor to the first model, the Walkabout/SX, released in 1990, was an architectural redesign allowing the laptop to be used as a general-purpose IBM PC compatible. The penultimate entry, the Walkabout/320, increased its predecessor's i386SX processor clock speed from 16 MHz to 20 MHz, while the last entry in the line, the Walkabout/386SL, replaced the processor with Intel's portable-centric i386SL processor clocked at 25 MHz.
