Fine pics. Silly commentary, and it's a PITA the guy only has a 300 baud
modem! The loading was _that_ slow.
I was wondering was the board gassing. Surely not 30 secs from the
solder. All that messing stops when it gets up to temprature, doesn't
it?

Greetings from Ireland. BTW, I get a lot of spam from Brazil. It all
hides behind apnic.net, who have the IPs and give them out to various
isps, I gather.
I can run 'whois' under linux on an IP and usually get the registered
name. But they're all registered to apnic.net. Apnic just say "F***
off and search with our website!" The website reveals nothing. Are you
in a good position to uncover those?
