That was unlucky - I plugged one into my 2gs once, but apart from the drive not
doing anything useful, nothing bad happened. I seem to recall a post by
possibly David Wilson or David Empson explaining why some 400K drive cables
worked and others didn't sometime recently, but I forget the reason. Sorry.

I have some DB19 male plugs spare if anyone wants to cough up the postage...
