I ran into the guy who made some pretty cool software which runs natively on the Acorn 3000 and some WonderMedia netbooks [WM8650, WM8850] which is called AMCS "Advanced Music Construction System" http://amcs.3rdevent.net/download.htm

Here are some from the event I went to at the Cambridge Centre for Computing History [ http://imgur.com/a/kZJaq ]

Here is a demo video tutorial on youtube.

I'm always amazed when meeting people who spend their time making such amazing software for music making and I thought people might like to know about it here.
