The first thing is the 3B2/310 is a direct replacement of the 3B2/300. They look exactly the same from a physical perspective. The much more important difference is the CPU on the 300 is an older verion. The 3B2/310 has a WE32100 CPU (That's Western Electric). This is an upgraded version of the earlier model and is running at a faster clock rate ( 10 Mhz ). There is an upgrade available for 300 to allow you to improve to a 3B2/310. I have a converted 3B2/300 as one of my home machines, so the process is quite simple to do. My system is now a 3B2/310 running at the 10 Mhz. You may find it difficult to aquire the upgrade kit in the future, since the 3B2/300 is a discontinued model, so if you have one of there beasties I would recommend upgrading as soon as you can.
