AmigaDOS developer Dr. Tim King has passed away

| Dr. Tim King was a prominent British computer scientist and developer
| who played a pivotal role in computing history by creating AmigaDOS,
| the foundational command-line and file-system layer of the iconic
| Commodore Amiga operating system. He passed away in late July 2026.
|
| Faced with an impossible six-month deadline when Commodore's original
| in-house operating system fell hopelessly behind schedule, Dr. King
| successfully adapted his own academic multitasking research to save
| the Amiga 1000 launch.
|
| ----------------------------------------------------------------------
|
| Academic Roots and TRIPOS
|
| Dr. King studied computer science at the University of Cambridge,
| earning his Ph.D. in 1979. During his time there, he worked
| extensively with TRIPOS (TRIvial Portable Operating System).
|
| The Architecture TRIPOS was an experimental, highly efficient
| preemptive multitasking system written primarily in BCPL (the
| programming language that directly preceded C).
|
| The 68000 Port In 1981, Dr. King spearheaded the task of porting
| TRIPOS from massive mainframes to the nascent Motorola 68000 micro-
| chip. This specific port would unknowingly alter the trajectory of
| personal computing.
|
| ----------------------------------------------------------------------
|
| The 1985 Amiga Emergency
|
| In 1984, Dr. King joined a Bristol-based software startup called Meta-
| ComCo as the Director of Research and Development, bringing the com-
| mercial rights of his 68000-ported TRIPOS with him.
|
| Meanwhile, across the Atlantic, the Amiga Corporation (newly bought by
| Commodore) was getting ready to launch the revolutionary Amiga 1000.
| While their custom multimedia chips and core kernel (Exec) were com-
| plete, their planned disk operating system (called CAOS) was struc-
| turally incomplete and months behind schedule.
|
| In a scramble, Commodore contracted MetaComCo in March 1985 to provide
| a replacement OS. Dr. King took his 68000 TRIPOS architecture and
| structurally wedged it right on top of the Amiga's custom Exec kernel.
| Working under brutal time constraints, Dr. King and his small team
| successfully delivered AmigaDOS in time for the computer's legendary
| July 1985 launch.
|
| ----------------------------------------------------------------------
|
| The TRIPOS Legacy in AmigaOS
|
| Because AmigaDOS was derived directly from TRIPOS, early versions of
| the Amiga carried distinct British academic quirks that millions of
| retro-computing enthusiasts still remember:
|
| BCPL Artifacts Large parts of early AmigaOS were written in BCPL
| rather than C, requiring a complex pointer-shifting system (BCPL
| pointers or "BSTRs") to talk to the rest of the machine.
|
| Directory Layouts The unusual standard Amiga system directories -
| such as C (for commands), L (for system handlers), and S (for
| scripts) - were inherited entirely from the TRIPOS file system layout.
|
| (Note: AmigaDOS was later completely rewritten from scratch in pure C
| for AmigaOS 2.0 to purge the remaining BCPL code while keeping the
| core command layout intact.)
|
| ----------------------------------------------------------------------
|
| Later Career: Perihelion and Helios
|
| Following his foundational work on the Amiga, Dr. King founded Peri-
| helion Software in 1986. He shifted his focus to the cutting edge of
| parallel processing and transputer hardware, designing a distributed,
| Unix-like operating system called Helios. He later pivoted to consumer
| tech, founding UK Online, one of the United Kingdom's earliest inter-
| net service providers.

Now that's pretty cool.

Seems like we never hear stories like this any more.

For supposing they should,
It would do them no good --
They'd lose it at once to the bold.

That's because nowadays he'd just port Linux.>
