Commodore Amiga 2000

The Amiga 2000 placed Amiga custom-chip technology in a large, highly expandable desktop chassis. Zorro slots, a video slot, processor slot and bridgeboard support made it suitable for professional video, publishing and PC-compatible applications.

Its expansion architecture made the A2000 a long-lived foundation for Video Toaster systems and other professional Amiga installations.

Notable Features

• The video slot permits direct access to Amiga video signals for genlocks and production hardware.
• Several motherboard revisions moved from OCS toward ECS components.

Historical Significance

• Its expansion architecture made the A2000 a long-lived foundation for Video Toaster systems and other professional Amiga installations.

Collector’s Notes

• Chipset and motherboard revision, Kickstart ROM, RAM expansion, accelerator cards and original keyboard or mouse should be documented.
• Memory, storage, displays and expansion hardware should be documented because configurations often changed during a system’s working life.
