Are u gonna South again?
Yeah, back to Antarctica for another year. I'm obviously insane. Or a sucker for the free food and cheap beer. There's no practical way of doing freight, so Amiga repairs and parts supplies will be on hold for a year.
As for repairing the A3000T, it's just a matter of sending the main board as costs of sending the entire computer would be prohibitive. You can airmail a 2.5kg main board around the world for around 44 Euro.
