The Howkins brothers tend to try to avoid adding non-RPC-related hardware emulation to devices, prefering to emulate real hardware unless there is a strong reason not to. Plus, a VFPEmulator would be useful on older real hardware as well as VirtualRPC. > I do wonder if trying to support > a 20+ year old platform just so that people can emulate it is all > that sensible. I don't disagree, but I imagine a significant proportion of users do use emulated systems. There's a bootstrap issue here: it may be better to provide some measure of support for old and new, at least for a while, before removing support for the old. > >Perhaps it might be time to try porting RISC OS to a qemu target so we > >can just plug in modern CPUs as they come along and use KVM on native > >ARM hardware. > > I think people have got it running under Qemu in the past, but I > seem to recall it was as modified version (of QEmu). Yeah, ideally RISC OS should be modified to work with unmodified Qemu (VirtIO or Versatile-type.) I suppose targeting real hardware is more interesting for those with knowledge and willpower to work on the RISC OS internals!
