Well it's good to know there's some still about anyway. If we're at a point 
where we *could* display them (running or not) one day then maybe I can talk

Hmm, I'll ask over on classiccmp to see if anyone there kept any hardware / 
docs too...

making that sort of stuff freely available, not charging for it.
