Gone, but not off the command line
Obituary: AmigaDOS developer Dr. Tim King has passed away
Fans say a quiet computer pioneer changed lives — and they’re finding out just how much now
TLDR: Dr. Tim King, who helped create the Amiga computer’s text-command system, has died, and commenters are reacting with a mix of shock, gratitude, and nostalgia. The big feeling is that even people who didn’t know his name now realize his work quietly pushed them into lifelong computer careers.
The tech world got a bittersweet shock with news that Dr. Tim King, a key figure behind the Amiga computer’s command system, died at the end of July. If that name doesn’t ring a bell, that was exactly part of the mood in the comments: one of the loudest reactions was basically, “Wait, I never knew his name — but he helped shape my whole career.” And honestly, that realization hit hard. For many old-school computer fans, King wasn’t a celebrity face; he was one of those behind-the-scenes builders whose work quietly changed how people used computers.
That emotional angle totally took over the discussion. One commenter called AmigaDOS their “gateway drug” to the command line — in plain English, the text-based way of controlling a computer that later led them to Linux and a tech career. That’s a huge tribute, and it turned a short obituary into a mini wave of gratitude. Others kept it simple and heartfelt with “Rest in peace” and memories of meeting him in person during later business ventures.
Was there big messy forum drama? Not really — but there was that classic internet contrast between deep nostalgia, blunt one-liners, and practical receipts. One user dropped a 2021 interview like a historian entering the chat, while another simply posted “say ‘RIP’” — which feels half memorial, half accidental meme. The result is a small but striking thread: less flame war, more collective realization that a low-profile pioneer left a very human mark.
