Yep, that looks like the one, thanks John. I can't find a supplier for
whole PSUs either although it looks like I can at least buy the plugs.
It looks like there's no standard wiring for them either and neither the
nominal manufacturer "Appliansys", or the actual manufacturer "Kink Yung
HK" make any mention of this box on ther websites, let alone have any
downloadable information about them :(

So I guess I'm on my own. Would people agree it's quite likely to
require +12v & +5v? Or is there a fair chance it's something else like
-12v & + 12v. And can anyone suggest a strategy for testing it out
without knackering it? or some things I can look for on the board to
give me a clue? I think I can see which are the ground pins but sadly
I'm no electronic expert :(
