What happened
Tim King, who ported Cambridge University's TRIPOS OS to the Motorola 68000 CPU—a port that became AmigaDOS for the original Commodore Amiga in 1985—has died aged 70. His rapid work on prototype Amiga hardware rescued Commodore's launch after its in-house CAOS OS project failed to deliver, and his BCPL-based code shaped AmigaDOS's command line, filesystem, and command structure.
Why it matters
This is computing history with no actionable takeaway for modern builders. The only mildly interesting technical note is how a message-passing kernel design (Amiga Exec) integrated cleanly with an externally sourced OS module—a pattern relevant to anyone assembling systems from independent components, but not enough to change what anyone ships today.
Discussion angle
Skip this one for the live segment unless filling a 'tech history minute' slot; the Exec message-passing architecture is the only thread worth a passing mention.
