Well I'm "missing" the Master Scientific board, plus A500 and the Casper 68k.

I don't know of *anyone* who has a Master Scientific, although I've had enough 
reports from dealers etc. who remember them that it seems they did actually 
exist.

Dave Moore seems to have the only A500 copro in the world, and that chap who 
turned up on c.s.a.h a few weeks back has the only Casper 68k board I've heard 
of...

Yes, I can't decide whether to count that or not - production quality hardware 
of course, but not *period* hardware...

Ooh, I'd not seen that before... ta!

Hmmm... if it's for the Dragon-based copro then look after it as it's probably 
the only copy around! :)

Someone else I know has a mystery 6809 disk too which I must grab an image of 
at some point...

Yep, it was a Eurocard board for the System range. I've got the manual, but no 
board or media (if I had the media I might be tempted to homebrew a board - 
schematics are in the manual IIRC)

If you start counting Eurocard boards then there's stuff like Control 
Universal's 6502, 6509 and 8088 boards too... :-)

(oh, I've unearthed some CUBE disks I think... no idea if they're just data 
yet or actual OS code though. Will image them in the next few days if I can)

Not to my knowledge, but then I hadn't heard about the CMS6809...

I've got some webpages almost finished, along the lines of Banksie's full 
Acorn machine list, but for second processors - must finish that off and upload!

cheers
