They are very different :)

There are lots of them on the market because people unloaded them after 
finding out the hard way that the cards weren't what people thought they 
were.  The ISL in the name has nothing to do with ISL - the Cisco 
proprietary analog to 802.1q.  They are actually Token Ring ISL adapters.

Save yourself the headaches and get something like a PA-2FE-TX if you need 
100baseTX for your 7206VXR.
