Commodore Amiga 4000T

The Amiga 4000T placed the A4000 architecture in a large tower with additional drive bays and improved expansion access. Commodore developed the machine before its collapse, with later production continued under successor ownership.

It was the final expandable tower form of the classic Commodore Amiga architecture.

Notable Features

• Both Commodore and later Escom-era production examples exist.
• Tower space makes it especially suitable for accelerator, graphics and storage upgrades.

Historical Significance

• It was the final expandable tower form of the classic Commodore Amiga architecture.

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.
