Greetings everyone,

I sent this message a few days ago and haven't heard anything from
anyone....   Is it that no one can help me or is it an RTFM issue and
everyone's been to polite to tell me?   ;-)

I've got people trying to sell me 21143-based cards and I'm pretty "gun-shy"
at the moment.....

Please help..
