This is not really a PIC question, but I really need some quick pointers
so apologies for a slightly OT posting...

I have just been asked to put together a design for an In-Car PC system
to go into emergency service vehicles, and which must radiate almost no
RF. I'm planning to go for a Mini-ITX form factor motherboard (the
CL1000 mobo) and a battery backed 12v PSU / UPS controlled by a PIC.

The whole caboodle will go into a custom made metal enclosure with a lot
of attention to RF shielding, to ensure that no RF leaks out of the vent
holes etc. I'm worried about how to prevent RF from escaping out of the
Kbd, VGA, Serial etc cables and was considering a 'filter-pcb' to filter
all communications to the outside world.

I know absolutely zilch about RF / EMC issues, so if anyone can point me
towards any URL's where I can learn the tricks of the trade, or just
advise what works and what doesn't, that would be great.

Thanks, Peter Moreton
