Sorry, I assumed it was a working prototype that was displayed . I read about it here - http://www.amigau.com/aig/boxer.html
Strange how Mick Tinker suddenly just gave up on the project.
I really hope the Clone A and Minimig do well, I'd love to get both. I think their development would have been greatly enhanced if they had all the BoXeR research to use with their designs though, rather than starting from scratch.
