Jess>"Is there anyway a VA5000 could be released (either free or very cheap) as a stopgap and a demo?"
I refer you to Graham Barnes reply (above). It's not a matter of having "a version" of VA to run on the Mac but to have a "commercial grade" application available to run thereon. I am sure if Graham and Aaron had the situation where VA5000 could run acceptibly on the Mac then the VARPC variant would be just as easily (and probably more sensibly) deployed on the Mac.
bluenose>I am not a big fan of emulation of RISC OS on other platforms (the image of nails and coffins keep popping into my head when I think about it....). But if you're going to allow it I am of two minds as to whether allowing something like "VA5000" (with presumably RO3.1) out there. I always thought the 77 objects per directory limit in that version of the OS was (at the very least) embarrassing - I would *not* want other platform users to think that RO was slow (emulators are) and surprising limited in the number of files they support per directory.
If the great and the good decided that RO could be "resurrected" by releasing RO on another platform (under emulation) - and the logic they used for doing this was convincing (I don't think it is though) - then I'd say release a *good* version of RO for demo not one from the time of Babbage and steam computers and 77 file limits etc., .....
