Amiga 3000
The Amiga 3000 was a computer from the Amiga series, produced between 1990 and 1992 by the Commodore.
He is a technical evolution of the Amiga 2000 and had already SCSI and Zorro 3 slots. In the first units delivered to customers the Kickstart ROM was similar to the Amiga A1000 forefather loaded as a file from hard disk - in contrast to the other Amiga models, in which this part of the operating system in ROM was sitting.
Later the Amiga 3000 was only delivered with ROMs for the kick start. For this purpose, but was contrary to the Amiga 500 or Amiga 2000 housed the kickstart into two ICs, since its CPU used a 32-bit wide data bus.
Hardware
- CPU: Motorola 68030/25 MHz or 16 MHz
- FPU: Motorola 68881 and Motorola 68882
- Chipset: ECS
- SCSI interface (up to 5 MB / s throughput)
- Built-in flicker fixer for the use of the graphics card with a conventional VGA monitor
- Internally Zorro 3 slots (similar to today's PCI slots in the PC )
- Operating system: AmigaOS 2.x ( later officially upgradeable by AmigaOS 3.1 by replacing the ROM )
- Kickstart ROM (BIOS): Initially, only bootstrap ROM (Super Kick Start) with boot menu for Kickstart 1.3 or 2.x from floppy, later the kickstart was firmly installed as ROM with the version 2.0, but could be replace by the new version 3.1.
- Maximum memory capacity on-board 16 MB Fast RAM ( for programs), and 2 MB Chip RAM ( for video and sound data). The RAM could be extended by a ZIP or DIP DRAM.
- Internal slot for CPU cards (usually called Turbo cards). So you could turn off the internal 68030 and replace it with the CPU on the accelerator. On these accelerator cards were often other extensions to find such as a faster SCSI port, fast RAM and a direct connection to an optional video card. Thus, it was possible to provide an A3000 with a turbo card, such as the Cyber Storm series of Phase 5, which with the 68040 - was armed or 68060 CPU and 4 MB to 128 MB of RAM. In a PPC card, which was also produced by Phase 5, it was possible to connect a fully 3D -capable graphics card directly on the PPC card.
- The Amiga 3000 gave it as a desktop and a tower version.
Model versions
The Amiga 3000 was it both as a desktop as well as a tower version ( Amiga 3000T, also initially called A3500 ). Furthermore, there was the Amiga version 3000UX that came on the market along with UNIX System V Release 4.
Under the model name Amiga 3000 exist only a few prototypes as a further development of the Amiga 3000th These include a digital signal processor and the AGA chipset used in series until the later models A1200 and A4000. The development was discontinued in favor of the successor model Amiga 4000 before the project gained market.
