No.  Acorn restructured last year to get the technology development
seperated from any education business by forming a jointly owned
venture with Apple called Xemplar (   Acorn RISC
Technologies ( is now providing all kinds of design
and implementation services based on RISC provessors (primarily ARM)

The lack of filetypes has been a concern for some time in the Acorn world
where we have only 4096 types.  Again these are registered in a single
place, but according to the people running the registry, there is no
shortage ...

So is it necessary to have all these different filetypes?  Does it lead to
file-type bloat with lots of different types for what are essentially the
same format files?

running NT4 with no trouble]
