Thanks for the empathy and advice Robert and Paul. Last night I ordered a 400/800 adapter from the Apple Store (it looked like the right shape ends in the blow-up pix) . It will arrive tomorrow. Sod going to the store -- the train fare would be 4x the delivery charge...
If it is the wrong one there will be a great howling and wailing and gnashing of teeth, not to mention rending of garments. Not that I'm Jewish -- just enjoy a bit of drama...
