Amiga Walker
The Amiga Walker, sometimes incorrectly known as the ''Mind Walker'', is a prototype of an Amiga computer developed and shown by Amiga Technologies in late 1995/early 1996. Walker was planned as a replacement for the A1200 with a faster CPU, better expansion capabilities, and a built-in CD-ROM. The ''Walker'' was never released; Escom and Amiga Technologies went bankrupt, and only two (three) prototypes were made. The case is unique and radically different from computers before it. The intention was also to make the motherboard available without the case so users could put it into a standard PC case. There were a number of other potential case designs of different sizes, the ''Walker'' motherboard could fit all of them; this allowed for expandability tailored to the user's requirements. When the Walker was announced, it was the subject of much discussion (and ridicule) within the Amiga user community, centering on the unconventional case design. Technical information Specifica ...

Amiga
Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. This includes the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprite (computer graphics), sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS. The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Am ...

Amiga Technologies
Amiga Corporation was a United States computer company formed in the early 1980s as Hi-Toro. It is most famous for having developed the Amiga computer, code named Lorraine. History In the early 1980s Jay Miner, along with other Atari staffers, had become fed up with management and decamped. In September 1982, they set up another chip-set project under a new company in Santa Clara, California, called Hi-Toro (which meant "high bull" to them, later renamed to Amiga), where they could have some creative freedom. There, they started to create a new 68000-based games console, codenamed Lorraine, that could be upgraded to a full-fledged computer. The initial start-up financing of Amiga Corporation was provided by three dentists in Florida, who later regained their investment once Commodore bought the company. To raise money for the Lorraine project, Amiga designed and sold joysticks and game cartridges for popular game consoles such as the Atari 2600 and ColecoVision, as well as an i ...

Amiga 1200
The Amiga 1200, or A1200 (code-named " Channel Z"), is a personal computer in the Amiga computer family released by Commodore International, aimed at the home computer market. It was launched on October 21, 1992, at a base price of £399 in the United Kingdom () and $599 in the United States (). History The A1200 was launched a few months after the Amiga 600, using a similar slimline design that replaced the earlier Amiga 500 Plus and Amiga 500. Whereas the A600 used the 16-bit Motorola 68000 of earlier Amigas, the A1200 was built around the 32-bit Motorola 68EC020. Physically, the A1200 is an all-in-one design incorporating the CPU, keyboard, and disk drives (including the option of an internal 2.5" hard disk drive) in one physical unit. The A1200's hardware architecture was later used as the basis for Commodore's Amiga CD32 game console in 1993. Initially, only 30,000 A1200s were available at the UK launch. During the first year of its life the system reportedly sold well ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escom (computer Company)
Escom AG (stylized in uppercase; previously Schmitt Computer Systems) was a German computer company, best known in Germany, the Netherlands, United Kingdom and the United States as the successful purchaser of Commodore International and the Amiga trademarks in 1995. Escom was founded by Manfred Schmitt of Darmstadt, Germany as the computer division of his music company in 1986. It became a separate company in 1991. In 1993, it became a publicly traded company, and it grew rapidly, controlling 11.2% of the market of German PCs by 1994. During 1992 and 1993, a British operation was set up with a distribution and assembly base in Irvine, North Ayrshire and a small number of retail stores. These followed the model established in Germany, with small town centre shops which would customise PCs to order, rather than the out of town superstores and mail order businesses which dominated the market in the United Kingdom. In February 1995, Escom's retail presence on the high streets of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorola 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 lacks some of the 6802 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 68020
The Motorola 68020 ("''sixty-eight-oh-twenty''", "''sixty-eight-oh-two-oh''" or "''six-eight-oh-two-oh''") 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 wafers, Motorola was still using metal gates and enhancement mode and their ...

Amiga Advanced Graphics Architecture
Amiga Advanced Graphics Architecture (AGA) is the third-generation Amiga graphic chipset, first used in the Amiga 4000 in 1992. Before release AGA was codenamed Pandora by Commodore International. AGA was originally called AA for Advanced Architecture in the United States. The name was later changed to AGA for the European market to reflect that it largely improved the graphical subsystem, and to avoid trademark issues. AGA is able to display graphics modes with a depth of up to s per pixel. This allows for in indexed display modes and (18-bit) in Hold-And-Modify (HAM-8) modes. The palette for the AGA chipset has 256 entries from (24-bit), whereas previous chipsets, the Original Chip Set (OCS) and Enhanced Chip Set (ECS), only allow out of 4096 or 64 colors in Amiga Extra Half-Brite (EHB mode). Other features added to AGA over ECS are super-hi-res smooth scrolling and 32-bit fast page memory fetches to supply the graphics data bandwidth for 8 bitplane graphics modes and wider ...

Kickstart (Amiga)
Kickstart is the bootstrap firmware of the Amiga computers developed by Commodore International. Its purpose is to initialize the Amiga hardware and core components of AmigaOS and then attempt to boot from a bootable volume, such as a floppy disk. Most Amiga models were shipped with the Kickstart firmware stored on ROM chips. Versions Commodore's AmigaOS was formed of both the Kickstart firmware and a software component provided on disk (with the software portion often termed as Workbench). For most AmigaOS updates the Kickstart version number was matched to the Workbench version number. Confusingly, Commodore also used internal revision numbers for Kickstart chips. For example, there were several Kickstart revisions designated as version 2.0. Version summary The first Amiga model, the A1000, required that Kickstart 1.x be loaded from floppy disk into a 256 KB section of RAM called the writable control store (WCS). Some A1000 software titles (notably ''Dragon's L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amiga Chip RAM
Chip RAM is a commonly used term for the integrated RAM used in Commodore's line of Amiga computers. Chip RAM is shared between the central processing unit (CPU) and the Amiga's dedicated chipset (hence the name). It was also, rather misleadingly, known as "graphics RAM". Direct memory access Under the Amiga architecture, the direct memory access (DMA) controller is integrated into the Agnus (Alice on AGA models) chip. Both the CPU and other members of the chipset have to arbitrate for access to shared RAM via Agnus. This allows the custom chips to perform video, audio, or other DMA operations independently of the CPU. As the 68000 processor used in early Amiga systems usually only accesses memory on every second memory cycle, Agnus operates a system where the "odd" clock cycle is allocated to time-critical custom chip access and the "even" cycle is allocated to the CPU: thus, for average DMA demand, the CPU is not typically blocked from memory access and may run without inter ...
