Summary from a recent talk
One of the longest-lived GUI operating systems in the world has its origins as an emergency project – specifically the means by which Acorn planned to rescue the original Archimedes operating system.
This is according to the original Acorn Arthur project lead, Paul Fellows, who spoke about the creation of RISC OS at the RISC OS User Group Of London, ROUGOL [after some helpful arrangements made by Liam Proven – Ed].
On Monday, your correspondent hosted and moderated a reunion of four of the original developers of Acorn’s RISC OS.
Fellows explained that participating were “Paul Fellows (VidC controller, Palette, I2C interface, Real Time Clock and EEPROM), Tim Dobson (Fonts, Audio and Utilities), Richard Manby (Graphics and Desktop), and Stuart Swales (Fileswitch and Heap Manager).”
