Amiga 3000
The Amiga 3000 was a computer from the Amiga series, manufactured between 1990 and 1992 by the Commodore company .
It is a technical further development of the Amiga 2000 and already had SCSI and Zorro 3 slots. The first models delivered was Kickstart - ROM similar to the Amiga forefather A1000 as a file from disk loaded - in contrast to the other Amiga models in which this part of the operating system was in ROM.
Later the Amiga 3000 was only delivered with ROMs for the kickstart . In contrast to the Amiga 500 or Amiga 2000, the Kickstart was accommodated in two ICs because its CPU used a 32-bit data bus.
Technical Equipment
- CPU : Motorola 68030 /25 MHz or 16 MHz
- FPU : Motorola 68881 or Motorola 68882
- Chipset : ECS
- SCSI -1 interface (maximum 5 Mbytes / s throughput )
- built- in flicker ( Amber ) for flicker-free playback of interlaced modes, and for direct connection of a conventional VGA - Monitor
- four internal Zorro III slots (comparable to the later PCI slots in the PC )
- two ISA slots (inline) for bridge cards
- Video slot for genlock or other video cards
- Operating system : AmigaOS 2.x (later officially upgradeable to AmigaOS 3.1 by exchanging the ROMs )
- Kickstart -ROM: At the beginning with Superkickstart: Bootstrap -ROM (Kickstart 1.4 beta) with boot menu for Kickstart 1.3 or 2.x from hard disk or floppy disk , later the Kickstart was installed as ROM with version 2.0. Kickstart 3.1 can be retrofitted.
- Maximum on-board memory expansion 16 MB FastRAM (for programs) and 2 MB chip RAM (for graphics and sound data). The RAM could be expanded with ZIP or DIP DRAM .
- Internal slot for CPU cards (usually called turbo cards ). This enabled the internal 68030 CPU to be switched off and replaced by the CPU on the accelerator card. Often there were other enhancements on these accelerator cards, such as a faster SCSI port, fast RAM and a direct connection to an optional graphics card. This made it possible to equip an A3000 with a turbo card, such as the Cyberstorm series from Phase5 , which was equipped with the 68040 or 68060 CPU and 4 MB to 128 MB RAM. With a PPC card, which was also produced by Phase5, it was possible to connect a fully 3D graphics card directly to the PPC card.
- The Amiga 3000 was also available as a tower version Amiga 3000T ; the main differences are the larger case and five Zorro III slots; four ISA slots (two of them inline with Zorro)
Model executions
The Amiga 3000 was available in both a desktop and a tower version ( Amiga 3000T , initially also called A3500). There was also the Amiga 3000UX version , which came onto the market together with UNIX System V Release 4.
Under the model designation Amiga 3000+ only a few exist prototypes as a further development of the Amiga 3000. These include a digital signal processor , as well as in the later models A1200 and A4000 used in Series AGA chipset . The development was stopped in favor of the successor model Amiga 4000 before the project was ready for the market.
