In an effort to drive that point home, Warden peppered chief government witness and Netscape CEO Jim Barksdale Tuesday with questions about his years as a salesman at IBM. Didn't Big Blue throw its weight around, too? "We were trained to behave as if we were a monopoly," said Barksdale, "because we were operating under a consent decree" -- which IBM had the good sense not to test, unlike Microsoft's wrangling last year. Touché. But didn't IBM do its own fair share of bundling products? Yes, but they were forced to unbundle in 1968, said the Netscape boss, which "gave rise to a whole new industry of hardware companies." Barksdale is back for more history lessons Wednesday. The Don will not be pleased.
