heh heh. I've got to fine my 32K one later as it's off to a new home. I'm 
keeping the Dragon 64 though I think (it's got the disk drive and a boat-load 
of original disk software, including OS-9)

Yes, somewhere. There was a two-issue article in a magazine (What Micro I 
think) called 'Dragon in the TUBE' way back when. I had the first part, and 
someone kindly scanned the second part for me a year or two ago.

Things are all upside-down here right now, but if nobody else has it then prod 
me again in a month or two and I can probably dig it out.

'something to run on it' is more tricky. I think the one covered in the 
article was designed to run FLEX (OS-9's little sibling), but of course the 
FLEX version produced for the article is nowhere to be found. FLEX for a 
different system could be adapted I suppose given sufficient determination to 
hack I/O drivers, but it's not exactly a trivial project.

Acorn did a 6809 board for the System bus, incidentally - so there was 
official 6809 hardware for Acorn machines.
