I plan of having a maxed-out T420 for fun. Thinking that Firewire isn’t particularly useful these days, but a second LAN port might. The Sub Card of T430 has a LAN port along with the USB and I was wpndering whether or not it’s compatible with the T420.
They physically look different so I’m going to go with no. The T430s has a lot more pins on the connector as well.
Even if they fit I doubt there’s an ethernet controller on that board so it wouldn’t work anyways.
I see. That’s too bad. Thanks!
