Re: RISC OS relicensed: now under Apache 2.0!

I'm aware that the post-Acorn history of RISC OS has been controversial at times, but I'm not fully up to speed on the detail and was wondering what this means for a single RISC OS codebase moving forwards. Does this mean that RISC OS 5 is likely to be the "standard" moving forward? (or is it alread...

Re: Updated BASIC Editor

P.S. if the editor has been behaving itself during your use of it, as it has been during mine, then the next version will probably also not be a beta. It's looking like the invasive changes of 1.41 haven't introduced any problems... My testing was primarily around the new keyboard changes, but I di...

Archimedes Mode 23 (high-resolution mono)

I recently realised that the original Archimedes supported a very high resolution (for the time) in Mode 23. 1152x896 with a refresh of 64Hz, albeit in only 2 colours. I can see how this may have been a useful mode for workstation-like displays, and certainly put it above some of the computers that ...
