ROUGOL logo Welcome to
RISC OS User Group Of London



ROUGOL is a not-for-profit organisation consisting of RISC OS users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.


Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?

Next meeting - Monday 19th February 2018 
ARMs, ARMs, everywhere - Bryan Hogan

...nor any bit to run (with apologies to Samuel Taylor Coleridge)

In the Science Museum there is a display about the history of micro processors (next to the gold BBC Micro!) which includes a video about the development af the ARM featuring Sophie Wilson and Herman Hauser. It finishes with Sophie saying "ARMs are everywhere". With ARM and their partners selling over a billion processors per month, this is without doubt, and the proliferaton of ARM boards has greatly benefitted RISC OS over the past 10 years or so.

However with the move to 64bit ARMv8 processors the future might not be so rosy. As raised in this thread on the ROOL forum, the next generation of ARMs might not be able to run RISC OS. We could be left with high end 64bit cpus and low end Cortex-M, neither of which is compatible with RISC OS.

During the meeting we will be looking at the history of changes to the ARM architecture, the effects they have had on compatibility with RISC OS and its applications, and what the options are for the future.
