Would either of you be able to help him? I have taken my XP1000 out of stor= age yesterday, but unfortunately it won't power on at the moment as the power supply needs= to be serviced. I have a 433au somewhere in my basement as well, but I haven't located it y= et. But it would also be better if Maciej could use a faster machine for his tests. Thanks, Adrian --=20 .''`.
