I'm back in London at the weekend, and if you're not the other end of
the world, I could take a look (with my electronic engineer's hat on),
have a little continuity test with a multimeter, and work out what the
pins do!  Designing a simple, cheap PSU would then be simple (though we
might choose to change the obscure 4-pin connector!).

Drop me a mail off-list, and I'll see if I can help.

Regards

Chris
