Apparently all sorted, but no pleasing some people.....
I advertised the tempest for £1k absolutely no offers, guy says he wants to buy, turns up, plays on it for half an hour and then offers me £900, then £950 and As i was begining to lose patience altogether coughed up the £1k.
Then sh*tty emails re the operating system which he knew when he took it away hadn't been updated.
Anyway thanks for all the help notes which I used to try and help the ungrateful person!
Cheers all and keep up the good work
