68030
The Motorola 68030 ("''sixty-eight-oh-thirty''") is a 32-bit microprocessor in the Motorola 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced ''oh-three-oh'' or ''oh-thirty''). The 68030 is essentially a 68020 with a memory management unit (MMU) and instruction and data caches of 256 bytes each. It added a burst mode for the caches, where four longwords can be loaded into the cache in a single operation. The MMU was mostly compatible with the external 68851 that would be used with the 68020, but being internal allowed it to access memory one cycle faster than a 68020/68851 combo. The 68030 did not include a built-in floating-point unit (FPU), and was generally used with the 68881 and the faster 68882. The addition of the FPU was a major design note of the subsequent 68040. The 68030 typically incr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 68000 Series
The Motorola 68000 series (also known as 680x0, m68000, m68k, or 68k) is a family of 32-bit computing, 32-bit complex instruction set computer (CISC) microprocessors. During the 1980s and early 1990s, they were popular in personal computers and workstations and were the primary competitors of Intel's x86 microprocessors.

Motorola 68040
The Motorola 68040 ("''sixty-eight-oh-forty''") is a 32-bit microprocessor in the Motorola 68000 series, released in 1990. It is the successor to the 68030 and is followed by the 68060, skipping the 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced ''oh-four-oh'' or ''oh-forty''). The 68040 was the first 680x0 family member with an on-chip Floating-Point Unit (FPU). It thus included all of the functionality that previously required external chips, namely the FPU and Memory Management Unit (MMU), which was added in the 68030. It also had split instruction and data caches of 4 kilobytes each. It was fully pipelined, with six stages. Versions of the 68040 were created for specific market segments, including the 68LC040, which removed the FPU, and the 68EC040, which removed both the FPU and MMU. Motorola had intended the EC variant for embedded use, but embedded processors during the 68040's time did not need t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atari TT030
The Atari TT030, more commonly known as the Atari TT, 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. In 1992, the TT was replaced by the Atari Falcon, a low-cost consumer-oriented machine with greatly improved graphics and sound capability, but with a slower and severely bottle-necked CPU. The Falcon possesses only a fraction of the TT's raw CPU performance. Though well priced for a workstation machine, the TT's high cost kept it mostly out of reach of the existing Atari ST market until after the TT was discontinued and sold at discount. The nascent open source movement eventually filled the void. Thanks to open hardware documentation, the Atari TT, along with the Amiga and Atari Falcon, were the first non-Intel machines to have Linux ported to them, though ...

Apollo Computer
Apollo Computer Inc. was an American technology corporation headquartered and founded in Chelmsford, Massachusetts. It was founded in 1980 by William Poduska (a founder of Prime Computer) and others. Apollo Computer developed and produced Apollo/Domain workstations in the 1980s. Along with Symbolics and Sun Microsystems, Apollo was one of the first vendors of graphical workstations. Like other computer companies at the time, Apollo produced much of its own hardware and software. Apollo was acquired by Hewlett-Packard in 1989 for US$476 million (equivalent to $ million in ), and gradually closed down over the period of 1990–1997. The brand (as "HP Apollo") was resurrected in 2014 as part of HP's high-performance computing portfolio. History Apollo was started in 1980, two years before rival Sun Microsystems. In addition to Poduska, the founders included Dave Nelson (engineering), Mike Greata (engineering), Charlie Spector (COO), Bob Antonuccio (manufacturing), Gerry St ...

Atari Falcon
The Atari Falcon030 (usually shortened to Atari Falcon), released in 1992, is the final personal computer from Atari Corporation. A high-end model of the Atari ST line, the machine is based on a Motorola 68030 CPU and a Motorola 56001 digital signal processor, which distinguishes it from most other microcomputers of the era. It includes a new VIDEL programmable graphics system which greatly improves graphics capabilities. Shortly after release, Atari bundled the MultiTOS operating system in addition to TOS. TOS remained in ROM, and MultiTOS was supplied on floppy disk and could be installed to boot from hard disk. The Falcon was discontinued in late 1993–a year after its introduction–as Atari restructured itself to focus completely on the release and support of the Jaguar video game console. The Falcon sold in relatively small numbers, mainly to hobbyists. Hardware The heart of the system is the 32-bit Motorola 68030 clocked at 16 MHz. It runs at about 4 M ...

Apollo/Domain
Apollo/Domain is a series of workstations that were developed and produced by Apollo Computer from to 1989. The machines were built around the Motorola 68k series of processors, except for the DN10000, which has from one to four of Apollo's RISC processors, named Apollo PRISM, PRISM. Operating system The original operating system is Apollo's own product called Aegis, which was later renamed to Domain/OS. The Aegis and Domain/OS system offers advanced features for the time, for example an object oriented filesystem, network transparency, diskless booting, a graphical user interface, and, in Domain/OS, interoperability with Berkeley Software Distribution, BSD, UNIX System V, System V, and POSIX. Hardware An Apollo workstation resembles a modern PC, with a base unit, keyboard, mouse, and screen. Early models are housed in short (about 2 feet high) 19" rack cabinets to be set beside a desk or under a table. The DN300 and later DN330 were designed as integrated units with the sy ...

Memory Management Unit
A memory management unit (MMU), sometimes called paged memory management unit (PMMU), is a computer hardware unit that examines all references to computer memory, memory, and translates the memory addresses being referenced, known as virtual memory addresses, into physical addresses in main memory. In modern systems, programs generally have addresses that access the theoretical maximum memory of the computer architecture, 32 or 64 bits. The MMU maps the addresses from each program into separate areas in physical memory, which is generally much smaller than the theoretical maximum. This is possible because programs rarely use large amounts of memory at any one time. Most modern operating systems (OS) work in concert with an MMU to provide virtual memory (VM) support. The MMU tracks memory use in fixed-size blocks known as ''pages''. If a program refers to a location in a page that is not in physical memory, the MMU sends an interrupt to the operating system. The OS selects a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 68020
The Motorola 68020 is a 32-bit microprocessor from Motorola, released in 1984. A lower-cost version was also made available, known as the 68EC020. In keeping with naming practices common to Motorola designs, the 68020 is usually referred to as the "020", pronounced "oh-two-oh" or "oh-twenty". The 020 was in the market for a relatively short time. The Motorola 68030 was announced in September 1986 and began deliveries in the summer of 1987. Priced about the same as the 020 of the time, the 030 was significantly faster and quickly replaced in 020 in almost every use. History 68000 and 68010 At the time the Motorola 68000 was designed, Motorola's design and fabrication services were outdated. Although even small companies like MOS Technology and Zilog had moved on to silicon gate depletion mode NMOS logic on ever-larger semiconductor wafer, wafers, Motorola was still using metal gates and enhancement mode and their largest fab worked on 4-inch wafers long after most lines had moved ...

Amiga
Amiga is a family of personal computers produced by Commodore International, Commodore from 1985 until the company's bankruptcy in 1994, with production by others afterward. The original model is one of a number of mid-1980s computers with 16-bit or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These include the Atari ST as well as the Macintosh 128K, Macintosh and Acorn Archimedes. The Amiga differs from its contemporaries through custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites, a blitter, and four channels of sample-based audio. It runs a pre-emptive multitasking operating system called AmigaOS, with a desktop environment called Workbench (AmigaOS), Workbench. The Amiga 1000, based on the Motorola 68000 microprocessor, was released in July 1985. Production problems kept it from becoming widely available until early 1986. While ...

Atari ST
Atari ST is a line of personal computers from Atari Corporation and the successor to the company's Atari 8-bit computers, 8-bit computers. The initial model, the Atari 520ST, had limited release in April–June 1985, and was widely available in July. It was the first personal computer with a bitmapped color graphical user interface, using a version of Digital Research's GEM (desktop environment), GEM environment from February 1985. The Atari 1040ST, released in 1986 with Megabyte, 1 MB of memory, was the first home computer with a cost per kilobyte of RAM under US$1/KB. After Jack Tramiel purchased the assets of the Atari, Inc. consumer division in 1984 to create Atari Corporation, the 520ST was designed in five months by a small team led by Shiraz Shivji. Alongside the Mac (computer), Macintosh, Amiga, Apple IIGS and Acorn Archimedes, the ST is part of a mid-1980s generation of computers with 16 or 16/32-bit processors, 256 kilobyte, KB or more of RAM, and computer m ...

Macintosh II
The Macintosh II is a personal computer designed, manufactured, and sold by Apple Computer from March 1987 to January 1990. Based on the Motorola 68020 32-bit CPU, it is the first Macintosh supporting color graphics. When introduced, a basic system with monitor and 20 MB hard drive cost . With a 13-inch color monitor and 8-bit display card, the price was about . This placed it in competition with workstations from Silicon Graphics, Sun Microsystems, and Hewlett-Packard. The Macintosh II was the first computer in the Macintosh line without a built-in display; a monitor rested on top of the case like the IBM Personal Computer and Amiga 1000. It was designed by hardware engineers Michael Dhuey (computer) and Brian Berkeley (monitor) and industrial designer Hartmut Esslinger (case). Eighteen months after its introduction, the Macintosh II was updated with a more powerful CPU and sold as the Macintosh IIx. In early 1989, the more compact Macintosh IIcx was introduced at a ...
