IBM 08L3148 10/100 EtherJet CardBus w/Cable

I have three of these, they are great for older Thinkpads without built-in ethernet connections. I had these for the TP600, TP560 series. These will also work in newer models if your on-board connector is dead.

Here is a link from Lenovo on the details:

This will work from Windows 95 to Windows XP along with OS2

$10.00 shipped.
