3Com EtherLink III TPO (3C509B-TPO) Network Adapter

Pros: 3Com name, parallel tasking -- offload processing to the NIC itself

Cons: if you don't need a managed card get the 3C905C-TX-NM instead

The Bottom Line: EXCELLENT. Must have. Don't need managed NIC? Get 3C905C-TX-NM

Review: Second only to the 3C905C-TX-NM, this is an excellent fast ethernet NIC. There are no negative aspects unless you consider reliability a downside. If you make your living repairing components then by all means avoid this one and buy something cheaply...
