Dragon 32/64 The Dragon 32 and Dragon 64 are home computers that were built in the 1980s. The Dragons are very similar to the TRS-80 Color Computer, and were produced for the European market by Dragon Data, Ltd., in Port Talbot, Wales, and for the US market by Tano of New Orleans, Louisiana. The model numbers reflect the primary difference between the two machines, which have 32 and 64 kilobytes of RAM, respectively.

MorphOS MorphOS is an AmigaOS-like computer operating system. It is a mixed proprietary and open source OS produced for the Pegasos PowerPC processor based computer, PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the EFIKA and mobileGT. Since MorphOS 2.4, Apple's Mac Mini G4 is supported as well, and with the release of MorphOS 2.5 and MorphOS 2.6 the eMac and PowerMac G4 models are respectively supported. The release of MorphOS 3.2 added limited support for PowerMac G5. The core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as Ambient desktop.

Sony SMC-70 The SMC-70 is a computer produced by Sony from 1982. Although it resembles a home computer, it was designed for professional video generation, for example in Cable television applications, and digital video effect generation. It was the first computer that used the just invented (also by Sony) 3.5" micro floppy disk drive that later became industry standard. It had a few distinctive aspects that set it aside from many of it contemporary systems. For example, it did not use a version of Microsoft BASIC, but its own Sony developed BASIC, and it could handle and display kanji characters.

Elektor TV Games Computer The Elektor TV Games Computer (TVGC) was a programmable computer system sold by Elektor in kit form from 1979. It used the Signetics 2650 CPU with the Signetics 2636 PVI for graphics and sound. These were the same chips as used in the Interton VC 4000 console family. A 2K monitor ROM written by Philips and a cassette interface were the most important differences between the TVGC and the Interton family. Many VC 4000 games were adapted versions of TV Games Computer games. It is possible to add cartridge slots to the TVGC to enable it to play console games, and the Hobby Module of the Acetronic console effectively transforms it into a basic TVGC.

MS/8 MS/8 or The RL Monitor System is a discontinued operating system developed for the PDP-8 in 1966 by Richard F. Lary. It was submitted to DECUS in 1970. It was a disk oriented system, faster than its predecessor, the 4K Disk Monitor System, with tricks to make it run quickly on DECtape based systems. MS/8 has since been replaced by P?S/8 and COS-310.

Plug computer A plug computer is an external device, often configured for use in the home or office as a compact computer. It consists of a high-performance, low-power system-on-a-chip processor with several I/O ports (USB ports, ...) and typically runs any of a number of Linux distributions. Most versions do not have provisions for connecting a display and are best suited as for running media server, back-up services, file sharing and remote access functions, thus acting as a bridge between in-home protocols such as Digital Living Network Alliance (DLNA) and Server Message Block (SMB) and cloud based services. There are, however, plug computer offerings that have analog VGA monitor and/or HDMI connectors, which, along with multiple USB ports, permit the use of a display, keyboard, and mouse, thus making them full-fledged, low-power alternatives to desktop and notebook computers.

IBM System/34 The IBM System/34 was an IBM midrange computer introduced in 1977. It was withdrawn from marketing in February, 1984. It was a multi-user, multi-tasking successor to the single-user System/32. Most notably, it included two very different processors, one based on System/32 and the second based on older System/3. Like the System/32 and the System/3, the System/34 was primarily programmed in the RPG II language. One of the machine's interesting features was an off-line storage mechanism that utilized "magazines" - boxes of 8-inch floppies that the machine could load and eject in a nonsequential fashion. Borrowing mainframe features such as programmable job queues and priority levels, the System/34 ran on 64K of memory.

IA-64 IA-64 (also called Intel Itanium architecture) is the instruction set architecture (ISA) of the Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was evolved and then implemented in a new processor microarchitecture by Intel with HP's continued partnership and expertise on the underlying EPIC design concepts. In order to establish what was their first new ISA in 20 years and bring an entirely new product line to market, Intel made a massive investment in product definition, design, software development tools, OS, software industry partnerships, and marketing. To support this effort Intel created the largest design team in their history and a new marketing and industry enabling team completely separate from x86. The first Itanium processor, codenamed "Merced", was released in 2001.

Interdata 7/32 and 8/32 The Model 7/32 and Model 8/32 were 32-bit minicomputers introduced by Perkin-Elmer after they acquired Interdata, Inc., in 1973. Interdata computers are primarily remembered for being the first 32-bit minicomputers. The 8/32 was a more powerful machine than the 7/32, with the notable feature of allowing user-programmable microcode to be employed.

TRS-80 Color Computer The Radio Shack TRS-80 Color Computer (also marketed as the Tandy Color Computer and affectionately nicknamed CoCo) is a line of home computers based on the Motorola 6809 processor. The Color Computer was launched in 1980, and lasted through three generations of hardware until being discontinued in 1991.

IBM System/360 The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover the complete range of applications, from small to large, both commercial and scientific. The design made a clear distinction between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the incompatible model 44 and the most expensive systems used microcode to implement the instruction set, which featured 8-bit byte addressing and binary, decimal and (hexadecimal) floating-point calculations.

DEC Professional (computer) The Professional 325 (PRO-325) and Professional 350 (PRO-350) were PDP-11 compatible microcomputers introduced in 1982 by Digital Equipment Corporation (DEC) as high-end competitors to the IBM PC.

DOS memory management In IBM PC compatible computing, DOS memory management refers to software and techniques employed to give applications access to more than 640 kibibytes (640*1024 bytes) (kiB) of "conventional memory". The 640 KiB limit was specific to the IBM PC and close compatibles; other machines running MS-DOS had different limits, for example the Apricot PC could have up to 768 KiB and the Sirius Victor 9000, 896 KiB. Memory management on the IBM family was made complex by the need to maintain backward compatibility to the original PC design and real-mode DOS, while allowing computer users to take advantage of large amounts of low-cost memory and new generations of processors. Since DOS has given way to Microsoft Windows and other 32-bit operating systems not restricted by the original arbitrary 640 KiB limit of the IBM PC, managing the memory of a personal computer no longer requires the user to manually manipulate internal settings and parameters of the system.

Amiga 1000 The Commodore Amiga 1000, also known as the A1000 and originally simply as the Amiga, is the first personal computer released by Commodore International in the Amiga line. It combines the 16/32-bit Motorola 68000 CPU which was powerful by 1985 standards with one of the most advanced graphics and sound systems in its class, and runs a preemptive multitasking operating system that fits into 256 KB of read-only memory and shipped with 256 KB of RAM. The primary memory can be expanded internally with a manufacturer supplied 256 KB module for a total of 512 KB of RAM. Using the external slot the primary memory can be expanded up to 8.5 MB.
