Umm.. actually, the priority of the other computers aren't taken into account; the ROM just checks to see if the line is busy; if it is, it waits until it isn't. I believe that the ROM source is still up on NVG, if anyone wants to take a peek :) BTW: You can connect more than 2 SAMs together over the network; it works as a loop; kinda like token ring, but not quite :) Simon
