Mark - I worked for an Apple / IBM / network dealer, during graduate school (1983-1985). The Corvus OmniNet solution was actually more popular for the Apple II -- especially with elementary schools (which was over 50% of store's Apple business). Apple, as you noted, had multiple network solutions (LocalTalk, AppleTalk in 1985) during the 1980s and Macintosh introduction (1984). LocalTalk https://en.m.wikipedia.org/wiki/LocalTalk AppleTalk https://en.m.wikipedia.org/wiki/AppleTalk --- In many ways, Steve Jobs "missed" the significance of networking for Macintosh launch (as did Microsoft with DOS) in this period ... even though he saw Xerox implementation, that eventually became 3Com. greg w9gb === -- Mark J.
