The Advanced Disc Filing System (ADFS) is a computing file system unique to the Acorn computer range and RISC OS-based successors.Initially based on the rare Acorn Winchester Filing System, it was renamed to the Advanced Disc Filing System when support for floppy discs was added (using a WD1770 floppy disc controller) and on later 32-bit systems a variant of a PC-style floppy controller.
Although Acorn never released a 68000 second processor product, Acorn's co-founder, Chris Curry, speculated on the nature of a 68000-based second processor product utilising its predecessor to the BBC Micro, the Proton. Indicating the need for "quite a full Proton system" acting as a front end to a 68000-based unit, the tentative projected cost ...

Risc PC was a range of personal computers launched in 1994 by Acorn, replacing the Archimedes series. The machines use the Acorn developed ARM CPU and were thereby not IBM PC-compatible. [3] [4] At launch, the original Risc PC 600 model was fitted as standard with an ARM 610, a 32-bit RISC CPU with 4KB of cache and clocked at 30MHz.
On 17 September 1998, Acorn finished a review of its business and decided to close the 'Workstation Division', the department developing Phoebe 2100, and all work stopped. [25] [26] [27] Acorn Computers' CEO Stan Boland said, "There is not a big enough market for the PC (Risc PC 2), which is largely for home use and games. It's an enthusiast's ...
