hostile takeover of Computervision in 1988
privatized via leveraged buyout in 1989

Prime Computer was founded in the early 1970s to develop and market clones of the successful Honeywell small computers.  Prime Computer developed a series of machines of increasing capability while maintaining backward compatibility by way of multiple instruction sets and "modal" operation.  Shortly after the stock market crash of 1987, Prime undertook the purchase of Computervision Corp. to exploit its graphics technology.

During 1988 the Computervision purchase turned into a hostile takeover, then as now a rare occurrence for technology companies. Unfortunately the cost of that takeover made Prime itself vulnerable to a leveraged buyout attack in 1989 from MAI Basic Four, a value-added reseller of Prime Computer equipment that was substantially smaller. To fend off that buyout, Prime Computer was taken private in late 1989 by a "White Knight" financial group from New York.
