  If you need to run Domain across them, HP/Apollo.

  If you're running TCP/IP services only on them, you can get
  them from HP/Apollo or else get the 3COM AT-bus ethernet
  card from any local warehouse (or 3COM), and save some bucks.

Actually, you can run Domain services and everything else on a 3-Com 505
ethernet board that you buy from 3-Com.  The only things that don't work are
boot ROM things like booting diskless and making system dumps over the
ether.

I've found that with educational discounts they aren't any cheaper from
3-Com, so we just buy them from Apollo.  But if you don't get the discount,
it may be cheaper to buy from 3-Com.  I think Apollo's price is around
$1000, 3-Com's is around $650.  Note that you can't use any of the cheaper
boards like the 501.  That's because they don't have the buffering and
on-board smarts required.

I've added the 505 board switch settings to the docs on dabo.ifs.umich.edu.
