Graeme Yeandle wrote The Quill, the program that let hundreds of people who could not write a line of machine code publish text adventures in the 1980s. He was not a games professional. He worked on mainframe computers for a living, wrote adventures in machine code for fun and swapped them with friends, and turned the tool he had built for himself into a product almost by accident.

How The Quill began
Sinclair User told the story in April 1985. Yeandle, “a friend of Tim and a systems analyst by profession”, mentioned to Tim Gilberts of Gilsoft that he had been swapping adventures he had written in machine code, among them Magic Castle. Gilberts borrowed the program and debugged it, and the two decided to build an adventure writing system on it. “Graham went off and I didn’t hear much from him for a few months,” Gilberts said. “He’s a pretty dedicated programmer and when he came back he had what amounted to a pre-production copy.” Because Yeandle worked freelance and lived some way away, most of the next year’s development was done by telephone.
Gilsoft published The Quill for the 48K ZX Spectrum in late 1983 at £14.95. It turned an adventure into a set of tables filled in through menus: vocabulary, locations, objects, messages, and the event and status tables that held the game’s logic. The Quill then saved the whole thing as a machine-code game that ran on its own. The entry on The Quill covers how it worked and how it was received; it sat in the CRASH readers’ chart through 1984, at number 34 in December.
Magic Castle
Gilsoft sold Magic Castle at £5.95, and CRASH reviewed it in May 1984 as “one of the earliest adventures written with The Quill”. You had to rescue a princess from the castle, and the game started you at a bend in a road beside a sign that read “Beware of Boobytraps”. CRASH’s reviewers died quickly: one was “despatched to hell within the first few moves”. “Graeme Yeandle is very sparse with his descriptions but his humour is lethal,” one wrote. Players who did not plan their moves began dying of thirst or exposure before they reached the castle.
PAW and S.W.A.N.
Yeandle stayed with Gilsoft’s later systems. CRASH listed him among the six authors of the Professional Adventure Writer in May 1987, and Sinclair User named him with Gilberts and Hugh Hamer-Powell as the developers of S.W.A.N., the System Without A Name, used for the 1988 adventure Mindfighter.
He and Gilberts did not agree about parsers. PAW could understand whole sentences, and Gilberts wanted it to; Yeandle thought commands should stay short. “‘Get the sharp knife and kill the large Orc with it’ is too complicated for a user to have to type in and get right,” he told Retro Gamer in 2005. “Entering commands needed to be kept simple, and point and click was probably the way to have done it.”
Later years
Yeandle died in January 2025, aged 70. Tim Gilberts, who attended his funeral at Margam Crematorium, wrote his obituary in Next Magazine. It recalled his early life on a farm, long cycling holidays with his brother and their mother, and his work on the Post Office Telephones mainframes, which was when he wrote The Quill in his spare time. In retirement he kept programming, taking on Advent of Code puzzles and helping others improve, and enjoyed long hikes and walks. He left a daughter and a grandson.
