[Lancaster] any old PCI ethernet cards

[max*]

Hi all,

possibly a bit of a long shot, but I'm wondering if anyone has any PCI 
ethernet cards (100mb+) knocking around? The network at 
www.seedsforchange.org.uk (a non profit org supporting local groups) is still 
working on 10Mb (some with BNC connections!) and while it's been fine so far, 
some heavy progs like firefox need more to drag more data down the line than 
the poor old cards can deal with (we're using thin clients with old 
machines). 

Currently my idea of a nice network is something that can run faster than 
1mb/s, so if anyone has any cards that they'd be happy to pass on to us we'd 
be very grateful! 

thankyou
