mrtd: you don't use any desktop systems for real-time control if you have any sense. RISC OS has been used for in control systems, running single tasking applications, so PMT and memory protection (which as we say over and over again RISC OS does have) aren't an issue. The interrupt latency is fairly low and predictable, and the OS is very lightweight not randomly deciding to go off and bugger around for an extended amount time, for no good reason.

The user interface to such as system is run on a separate machine which again RISC OS is good for. Ideally engineers prefer a full screen front end, controlled by nice big function keys on a sealed keyboard which can be pressed with oily hands, rather than a fiddly windows moved around by a mouse which tends to stop working after a few hours in such conditions. Such a front end can easily switch back and forth to the desktop for doing more advanced tasks such as printing, or playing !Mines :)
