A pocket computer is a class of handheld computer characterized by very short displays and calculator-style alphanumeric keypads. Pocket computers occupy a small footprint, allowing the unit to be comfortably stashed in one's pocket when on the go, and usually weigh less than 1 pound (0.45 kg). Many feature a port for an expansion chassis, allowing the computers to be used with external peripherals.
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.

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.
DECpc was a wide-ranging family of desktop computers, laptops, servers, and workstations sold by Digital Equipment Corporation. The vast majority in the family are based on x86 processors, although the APX 150 uses DEC's own Alpha processor. The line was DEC's first big break into the IBM PC compatible market.
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.
The SupersPort is a line of PC-compatible laptops manufactured by Zenith Data Systems and sold from 1988 to 1993.

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.
