What if Amiga development had never stopped?

Ceylon isn't rebuilding an old Amiga. It's exploring what some of the strongest ideas behind personal and workstation computing might have become if they had kept evolving — and trying to build that computer.

Illustrative retro archival-style poster: a fictional VHS-tape-styled historical dossier for a fabricated company "Ceylon Technologies," depicting its corporate sign outside an office building in fog, with an invented bankruptcy date of April 29, 1994, and fabricated "cancelled" technical blueprint panels (bus architecture, chipset tape-out, asset liquidation). Not a real company, event, or document.

What are we building?

What is Project Ceylon

A general-purpose workstation

The long-term direction is a reasonably priced, general-purpose professional workstation.

Not a gaming machine. Not a music machine, a video machine, a development machine or a business machine. One computer that does all of those things well, with business productivity and creative work treated as equal first-class concerns.

The practical test we keep coming back to is simple enough to say and hard enough to build: could somebody sit down at Ceylon on Monday morning and reasonably leave their other workstation turned off?

That's an engineering goal, not a product claim. We're not there. The status page says how far along things actually are.

Principles, not implementations

Ceylon studies older systems to recover principles, not implementations. Historical inspiration is a source of questions. It isn't the source of final answers.

Worth carrying forward

  • Responsiveness
  • Asynchronous operation
  • Efficient use of resources
  • Modularity and coherent system design
  • Specialized subsystems doing specialized work
  • Multimedia as a first-class workload
  • Programmability
  • Understandable system behavior
  • Local ownership
  • Applications that cooperate

Worth leaving behind

  • Old CPU families and chipsets
  • Small address spaces
  • 1980s threat models
  • Period graphics and memory limits
  • Old peripheral assumptions
  • Historical security models

A professional computer that stays personal

A workstation should stay useful because its owner owns it. Local work should remain viable. Online services can extend the computer; they shouldn't decide whether it works.

Where Ceylon stands

A dated snapshot of what the public Development Journal had reported by September 25, 2026 — what was working, what was still in development, and what hasn’t been claimed. Not a roadmap or a promise.

Full status snapshot

Working on the reference machine

  • Boots on the newer microkernel foundation, rebuilt and re-booted repeatedly rather than trusted after one run
  • Multiprocessor support
  • IOMMU
  • System controller starts; PCI enumeration works
  • USB controller initializes; keyboard input arrives through the virtual USB hardware
  • Block storage: devices identified, volumes published, read, write and flush

As reported in the journal on September 23, 2026.

In development

  • NuGUI compositor, window management and input qualification — the usable desktop
  • User-facing persistence: an application saves something, the machine reboots, and it comes back
  • The native terminal and NuDOS command environment; a file manager
  • NuBASIC Level 1, moving from specification into implementation, with a simple editor
  • Kirk (local service and application coordination): long-duration qualification
  • Logging and recovery evidence

Work in progress and published plans as of September 23–25, 2026 — not commitments.

Evidence

Real screenshots, recordings and bench photos — when they exist.

Media
No project screenshots have been published yet. When real Ceylon screenshots, recordings or bench photos are published, they appear here with their dates and sources. Nothing on this site presents a stock photo, a render or a mock-up as Ceylon.
