Just to use a small example of pin2000 and its no biggy if you are savvy, but my rfm has a different monitor manufacturer to my swep1. To put my replacement new WG brand monitor into the rfm, I need to reconfigure the plugs. Not so for the swep1as it has an old WG but both games involve structural mounting mods to get the new crt in. So I think this illustrates how even Williams changed their minds on pc hardware that didn't make the rfm spare plug and play and that was in one year.
