A1200
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] |
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 ...

Amiga CD32
The Amiga CD32 (stylized as Amiga CD32) is a home video game console developed by Commodore as part of the Amiga line, as well as the final hardware to be developed by the company. Released in September 1993 in Europe, Australia, Canada, and Brazil, it was marketed as the "first" 32-bit games console and is essentially a keyboard-less Amiga 1200 personal computer without the I/O ports, but with the addition of a CD-ROM drive in place of floppy and a modified Advanced Graphics Architecture chipset for improved graphical performance. Unlike Commodore's CDTV released two years prior, the CD32 was designed specifically as a games machine. The majority of CD32 game software were ports of existing Amiga 1200 or Amiga 500 titles, and many did not take advantage of CD capabilities like CD music or full-motion video. While it had sold middingly in European markets, the console was withdrawn from sale after only a short time as Commodore filed for bankruptcy in April 1994. Histo ...

AmigaOS
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola Motorola 68000 family, 68000 series of 16-bit and 32-bit microprocessors. Later versions, after Commodore's demise, were developed by Haage & Partner (AmigaOS 3.5 and 3.9) and then Hyperion Entertainment (AmigaOS 4.0-4.1). A PowerPC microprocessor is required for the most recent AmigaOS 4-release. AmigaOS is a single-user operating system based on a preemptive multitasking kernel (operating system), kernel, called Exec (Amiga), Exec. It includes an abstraction of the Amiga's hardware, a disk operating system called ''AmigaDOS'', a windowing system Application programming interface, API called Intuition (Amiga), ''Intuition'', and a desktop environment and file manager called Workbench (AmigaOS), ''Workbenc ...

Amiga 500
The Amiga 500, also known as the A500, was the first popular version of the Amiga home computer, "redefining the home computer market and making so-called luxury features such as multitasking and colour a standard long before Microsoft or Apple sold these to the masses." It contains the same Motorola 68000 as the Amiga 1000, as well as the same graphics and sound coprocessors, but is in a smaller case similar to that of the Commodore 128. Commodore International, Commodore announced the Amiga 500 at the January 1987 winter Consumer Electronics Showat the same time as the high-end Amiga 2000. It was initially available in the Netherlands in April 1987, then the rest of Europe in May. In North America and the UK it was released in October 1987 with a list price. It competed directly against models in the Atari ST line. The Amiga 500 was sold in the same retail outlets as the Commodore 64, as opposed to the computer store-only Amiga 1000. It proved to be Commodore's best-selling m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amiga 600
The Amiga 600, also known as the A600, and full title Commodore Amiga 600, is a home computer introduced in March 1992. It is the final Amiga model based on the Motorola 68000 and the 1990 Amiga Enhanced Chip Set. A redesign of the Amiga 500 Plus, it adds the option of an internal hard disk drive and a PCMCIA port. Lacking a numeric keypad, the A600 is only slightly larger than an IBM PC keyboard, weighing approximately 6 pounds (2.72kg). It shipped with AmigaOS 2.0, which was considered more user-friendly than earlier versions of the operating system. Like the A500, the A600 was aimed at the lower end of the market. Commodore intended it to revitalize sales of the A500-related line before the introduction of the 32-bit Amiga 1200. According to Dave Haynie, the A600 "was supposed to be cheaper than the A500, but it came in at about that much more expensive."Haynie, Dave"Re: Amiga CPU is similar to Mac CPU" Usenet (comp.sys.mac.hardware.misc).

Commodore International
Commodore International Corporation was a home computer and electronics manufacturer with its head office in The Bahamas and its executive office in the United States founded in 1976 by Jack Tramiel and Irving Gould. It was the successor company to Commodore Business Machines (Canada) Ltd., established in 1958 by Tramiel and Manfred Kapp. Commodore International (CI), along with its U.S. subsidiary Commodore Business Machines, Inc. (CBM), was a significant participant in the development of the home computer industry, and at one point in the 1980s was the world's largest in the industry. The company released its first home computer, the Commodore PET, in 1977; it was followed by the VIC-20, the first ever computer to reach one million units of sales. In 1982, the company developed and marketed the world's best selling computer, the Commodore 64; its success made Commodore one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at ...

Amiga 4000
The Amiga 4000, or A4000, from Commodore is the successor of the Amiga 2000 and Amiga 3000 computers. There are two models: the A4000/040 released in October 1992 with a Motorola 68040 CPU, and the A4000/030 released in April 1993 with a Motorola 68EC030. The Amiga 4000 system design was generally similar to that of the A3000, but introduced the Advanced Graphics Architecture (AGA) chipset with enhanced graphics. The SCSI system from previous Amigas was replaced by the lower-cost Parallel ATA. The original A4000 is housed in a beige horizontal desktop box with a separate keyboard. Later, Commodore released an expanded tower version called the A4000T. The machine is reported to have sold 11,300 units in Germany. Technical information Processor and RAM The stock A4000 shipped with either a Motorola 68EC030 or 68040 CPU, 2 MB of Amiga Chip RAM and up to 16 MB of additional RAM in 32-bit SIMMs. There is a non-functional jumper that was intended to expand ...

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 ...

AAA Chipset
The AAA chipset (Advanced Amiga Architecture) was intended to be the next-generation Amiga multimedia system designed by Commodore International. Initially begun as a secret project, the first design discussions were started in 1988, and after many revisions and redesigns the first silicon versions were fabricated in 1992–1993. The project was stymied in 1993 based on a lack of funds for chip revisions. At the same time AAA started first silicon testing, the next generation Commodore chipset project was in progress. While AAA was a reinvention and huge upgrade of the Amiga architecture, project Hombre was essentially a clean slate. It took what was learned from Amiga and went in new directions, which included an on-chip CPU with a custom 3D instruction set, 16-bit and 24-bit chunky pixel display, and up to four 16-bit playfields running simultaneously. Hombre also embraced the PCI bus, which was seen as the future for main board interconnect and expansion going forward. Des ...

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 typically increases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
