The RDI PowerLite is a series of SPARC-based laptops and mobile workstations marketed by RDI Computer Corporation.
PowerLite models were all based on Sun's sun4m architecture, and were fully compatible with all operating systems and software developed for them. All models had support for two 2.5" SCSI hard drives and one floppy drive or PCMCIA adapter, or three 2.5" SCSI hard drives. 104-key keyboards and trackballs were also included. In addition, there were docking stations available, with SBus slots and additional 3.5" hard drive bays.
A ruggedized model was also released, the RUGGEDIZED PowerLite, with one floppy drive and PCMCIA standard, and an optional CD-ROM or DAT drive.

Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088-based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.
The Zip drive is a removable floppy disk storage system that was introduced by Iomega in late 1994. Considered medium-to-high-capacity at the time of its release, Zip disks were originally launched with capacities of 100 MB, then 250 MB, and finally 750 MB.
The FM Towns is a Japanese personal computer, built by Fujitsu from February 1989 to the summer of 1997. It started as a proprietary PC variant intended for multimedia applications and PC games, but later became more compatible with IBM PC compatibles. In 1993, the FM Towns Marty was released, a game console compatible with existing FM Towns games.
RISC iX is a discontinued Unix operating system designed to run on a series of workstations based on the Acorn Archimedes microcomputer. Heavily based on 4.3BSD, it was initially completed in 1988, a year after Arthur but before RISC OS. It was introduced in the ARM2-based R140 workstation in 1989, followed up by the ARM3-based R200-series workstations in 1990.
The SPARCstation 1 is the first of the SPARCstation series of SPARC-based computer workstations sold by Sun Microsystems. The design originated in 1987 by a Sun spin-off company, Unisun, which was soon re-acquired. The SPARCstation 1 has a distinctive slim enclosure and was first sold in April 1989, with Sun's support ending in 1995.
The Atari TT030 is a member of the Atari ST family, released in 1990. It was originally intended to be a high-end Unix workstation, but Atari took two years to release a port of Unix SVR4 for the TT, which prevented the TT from ever being seriously considered in its intended market.
DeskStation Technology was a manufacturer of RISC-based computer workstations intended to run Windows NT. DeskStation was based in Lenexa, Kansas.
Tadpole Computer was a manufacturer of rugged, military specification, UNIX workstations, thin client laptops and lightweight servers.
The Multia, later re-branded the Universal Desktop Box, was a line of desktop computers introduced by Digital Equipment Corporation on 7 November 1994. The line is notable in that units were offered with either an Alpha AXP or Intel Pentium processor as the CPU, and most hardware other than the backplane and CPU were interchangeable. Both the Alpha and Intel versions were intended to run Windows NT.
Toughbook is a line of rugged computers produced and marketed by Panasonic Corporation. The Toughbook, introduced in 1996 with the CF-25, is designed to withstand outside forces which would damage or destroy normal laptops. Toughbook mobile computers are used in a wide variety of industries, including construction, defense, emergency services, government, healthcare, law enforcement, manufacturing, oil, gas, telecom, and utilities. The Toughbook brand mainly competes with other lines of rugged computers, such as Dell's Rugged Extreme.
The SPARCstation 20 or SS20 is a discontinued Sun Microsystems workstation introduced in March 1994 based on the SuperSPARC or hyperSPARC CPU. It is one of the last models in the SPARCstation family of Sun "pizza box" computers, which was superseded by the UltraSPARC design in 1995.
The SPARCstation 10 is a workstation computer made by Sun Microsystems. Announced in May 1992, it was Sun's first desktop multiprocessor. It was later replaced with the SPARCstation 20.
SPARCstation 5 or SS5 is a workstation introduced by Sun Microsystems in March 1994. It is based on the sun4m architecture, and is enclosed in a pizza-box chassis. Sun also offered a SPARCserver 5 without a framebuffer. A simplified, cheaper version of the SS5 was released in February 1995 as the SPARCstation 4. Sun also marketed these same machines under the "Netra" brand, without framebuffers or keyboards and preconfigured with all the requisite software to be used as web servers. An estimated 400,000+ SPARCstation 5s were sold.
The Sun386i is a discontinued hybrid UNIX workstation/PC compatible computer system produced by Sun Microsystems, launched in 1988. It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems.
The Sony NEWS is a series of Unix workstations sold during the late 1980s and 1990s. The first NEWS machine was the NWS-800, which originally appeared in Japan in January 1987 and was conceived as a desktop replacement for the VAX series of minicomputers.
The SPARCstation 2, or SS2 is a SPARC workstation computer sold by Sun Microsystems. It is based on the sun4c architecture, and is implemented in a pizza box form factor.
The ICL DRS was a range of departmental computers from International Computers Limited (ICL). Standing originally for Distributed Resource System, the full name was later dropped in favour of the abbreviation.
The SPARCstation IPX is a workstation that was sold by Sun Microsystems, introduced July 1991. It is based on the sun4c architecture, and is enclosed in a lunchbox chassis.
The Ultra 60 is a fairly large and heavy computer workstation in a tower enclosure from Sun Microsystems. The Ultra 60 was launched in November 1997 and shipped with Solaris 7. It was available in several specifications.
