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.

Development

The LTE Lite series was the second generation of LTE, a notebook family introduced three years earlier in 1989. The first two entries in the LTE Lite series, the LTE Lite/20 and the LTE Lite/25, were the first computers released under Eckhard Pfeiffer's tenure as CEO. Pfeiffer assumed the position on October 24, 1991; he replaced Compaq co-founder Rod Canion, who was ousted from the company a day after the company posted its first quarterly loss—$70.3 million—leading to Compaq's first ever round of layoffs.^[1]

The LTE Lites improved the battery life and quality of its liquid-crystal display panels while reducing weight. The LTE Lite/20 and LTE Lite/25 introduced suspend and hibernation modes, as well as a BIOS password and a Kensington slot for added security.^[1] Starting with the LTE Lite/25C and LTE Lite/25E, a trackball was built into the display housing on the right side, with the left- and right-click buttons on the reverse side of the housing.^[2] An internal modem, 9600-baud, was optional.^[1]

Manufacturing of the LTE Lites was initially performed at Compaq's plant in Houston, Texas. Compaq used Citizen Watch of Japan as manufacturer for its monochrome passive-matrix LCDs and as a second source for manufacturing of the entire systems.^[2]^[3] Citizen later became its sole manufacturer.^[4] Production of the LTE Lite was again moved from Citizen in Japan to Compaq's overseas plant in Singapore in 1994—Compaq citing wanting to fill vacant production lines in that plant, which also manufactured its Contura line of budget notebooks.^[4] The hard disk drives meanwhile were manufactured by Conner Peripherals.^[2]

The monochrome passive-matrix LCDs used in the LTE Lites were a co-development between Compaq and Citizen, who developed ways to reduce motion persistence ("ghosting") and crosstalk interference patterns ("bleeding") common in their super-twisted nematic displays.^[3] The monochrome active-matrix LCDs used in the Lite/25E and Lite 4/25E were manufactured by Hosiden. These were the same LCDs used by Apple in some entries of their PowerBook 100 series.^[5] Compaq were the only notebook manufacturer besides Apple to make use of active-matrix monochrome LCDs.^[6]^[7]

The LTE Lite/20 and LTE Lite/25 (including all submodels) used Intel's low-powered, portable-specific 80386SL processor.^[8]^[9]^[7]^[10] Compaq became the first laptop to feature Intel's later portable-specific 80486SL with the announcement of the LTE Lite 4/25 in November 1992.^[11]

Reception

Reviewing the LTE Lite/25 and LTE Lite/20, Rick Ayre of PC Magazine called the two laptops "state-of-the-art" and high-priced, with a good display and keyboard but with compromised battery life compared to their predecessor, the LTE 386s/20.^[8] The LTE Lites were the top-performing 386 laptops in terms of graphics performance and among the top five of 386 laptops in terms of rendering graphics within Windows.^[12] The magazine also rated it among the fastest in its processor class in terms of memory speed and data processing but found its hard disk performance mediocre.^[8] Mitt Jones, also of PC Magazine, called the battery life "somewhat lackluster" but praised the versatility of the user-definable power consumption modes and found the display bright and sharp with minimal ghosting.^[3]

Michael Caton of PC Week , reviewing the LTE Lite/25, praised its battery life, case design, ease of use, and keyboard layout. PC Week's test lab compared it to Zenith Data Systems' MastersPort 386Le and found that the LTE Lite won out over the MastersPort under a stress test load: 3 hours compared to 2 hours and 11 minutes. Caton wrote that the power consumption modes were easy to configure. Similarly, the keyboard's hotkey functions allowed him to perform functions like disabling the external monitor or setting the speaker volume more easily compared to contemporaneous laptops, which required the user exit out to DOS and run a function utility. Caton called the case design "sturdy ... typical of Compaq notebooks" and the keyboard "well laid out".^[13] Caton found reservation with the keyboard's switches, which he deemed soft, and, the passive-matrix display, which exhibited ghosting most noticeably under Windows.^[13]

Andreas Uiterwuk and Siobhan Nash of InfoWorld , reviewing the LTE Lite/25C, rated the active-matrix color LCD well, with brilliant colors and a wide viewing angle, that exhibited no crosstalk interference patterns. The reviewers found the US$4,999 selling price "hefty" and found that it performed 9 percent slower than its monochrome counterpart but on par with its competitor in the active-matrix color notebook arena, NEC's UltraLite SL/25C.^[9] Nash and Earl Angus of the same publication, reviewing the LTE Lite/25E, called the laptop's $2,917 selling price "a pretty good deal" with its active-matrix monochrome display and equivalent processor to the LTE Lite/25C. Like Caton the reviewers found the keyboard too soft, the key travel too shallow, but they were impressed with its display, which exhibited "little bleeding".^[7]

Larry Blasko of the St. Petersburg Times , reviewing the LTE Lite 4/25E, found its relatively high price justified by its processing power, display, and keyboard and called the laptop overall a "first-rate job".^[10] In particular, Blasko found that the monochrome, active-matrix panel rendered "nice, crisp text and graphics" and that the keyboard had a "crisp touch" that held up under his heavy typing style.^[10] Blasko's unit scored 53.4 on the Norton index, meaning that it was over 50 times faster than a PC XT and 1.5 times faster than a 33-MHz Compaq Deskpro 386, which had a rating of 34.7. Blasko wrote that the LTE Lite was snappy running Windows 3.1.^[10]

Legacy

The LTE Lite series proved very successful for Compaq, accounting for half of their entire notebook sales in 1993 alone.^[14] Between 1992 and 1993, Citizen had manufactured between 20,000 and 25,000 LTE Lite units each month.^[4] The LTE Lite series was replaced by the LTE Elite series in March 1994. The LTE Elite series increased the memory, processors, and networking capabilities and moved the AC adapter to within the notebooks' chassis, eliminating the need for external bricks.^[14]

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 8085- and 8088-based computer capable of running both CP/M and MS-DOS.

The ActionNote was a series of notebook-sized laptops 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 650 and 660 series, which were produced by Compal, and 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.

The PB286LP, released in 1989, was Packard Bell's first laptop computer. The laptop featured an 80C286 processor clocked at 12 MHz and 1 MB of RAM, along with a single ISA expansion slot. Packard Bell released the PB286LP in 1989 among a slew of products aimed at the corporate market. Technology writers gave it mostly positive reviews, although some noted its 16-lb weight as hefty and its monochrome LCD as somewhat flawed. Originally only capable of CGA-mode graphics, the laptop was updated in 1990 to support VGA. Packard Bell discontinued the PB286LP in 1991, in favor of more-compact, notebook-sized computers.

The Sharp PC-4500 is a line of laptop computers released by Sharp Corporation in 1987. The line comprises the PC-4501, the PC-4502, and the PC-4521. The PC-4501 is a bare-bones unit with only 256 KB of RAM stock, only one floppy drive, no backlighting, and no built-in numeric keypad; the PC-4502 and PC-4521 bumps the stock RAM to 640 KB and includes the latter two features while providing either two floppy drive (PC-4502) or one floppy drive and a 20 MB hard drive (PC-4521). Prices on the line initially ranged from $1,295 to just under $3,000; the PC-4501 was later sold for $995, becoming one of the first sub-$1,000 laptops available on the market. The PC-4500 line received mixed, mostly positive, reviews on its release in September 1987.

The SupersPort is a line of PC-compatible laptops manufactured by Zenith Data Systems and sold from 1988 to 1993. The first two main entries in the SupersPort line included either an Intel 80286 microprocessor clocked at 12 MHz or an 8088 processor clocked at 8 or 4.77 MHz, switchable. Later entries included the 386SX, 486SX and 486 processors. The SupersPort 286 in particular was one of the top-selling laptops of the late 1980s, although Zenith's position in this segment faltered by the early 1990s.

Airis Computer Corporation was a short-lived mail-order American computer company active from 1989 to 1993. Its only product, the Airis VH-286 notebook, was widely anticipated for its slim yet powerful design and long-battery life, owing to the use of disposable C batteries as its primary source of power. The product was met with a number of delays owing to FCC regulations and other unspecified reasons. Airis collapsed in 1993, amid the conclusion of a trademark infringement lawsuit with Harris Corporation; Airis' rights to their namesake trademark lapsed in late 1992. Both Byte and PC Magazine claim that Airis never sold any units of the laptop.

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. Due to several recalls and a delayed rollout of the machines, the LTE Elite was overall a sales disappointment for Compaq, with rival Toshiba overtaking them as the top laptop maker in the United States in 1994 and 1995.

The LTE 5000 series was a series of notebook-sized laptops under the LTE line manufactured by Compaq from 1995 to 1997. The LTE 5000 series was Compaq's first laptop with Pentium processors from Intel. The line of computers were co-developed between Compaq and Inventec of Taiwan and were manufactured entirely by Inventec overseas. The LTE 5000 series was the last generation in the LTE line, Compaq replacing it with the Armada line in 1997.

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 IBM PC–compatible notebook and helped launch the fledgling PC notebook industry, which had seen earlier attempts fail due to the use of novel but nonstandard data storage.

<span class="mw-page-title-main">Data General Walkabout</span>

The Walkabout is a family of notebook-sized laptops 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.

A notebook computer or notebook was historically a laptop whose length and width approximate that of letter paper.

The CF-V21P is a notebook-sized laptop released by Panasonic in 1993. It was the first notebook computer to have an integrated CD-ROM drive as an option, albeit it only supports up to 3.5-inch-diameter mini CDs instead of standard 5.25-inch-diameter discs. It was discontinued in 1994.
