In the 1970s, the US Department of Justice brought an antitrust lawsuit against IBM, claiming it was using unlawful practices to knock out competitors. At this time, IBM had been about to consolidate its entire line (System/370, 4300, System/32, System/34, System/38) into one "family" of computers with the same ISAM database technology, programming languages, and hardware architecture. But after the lawsuit was filed, IBM decided it would have two families: the System/38 line, intended for large companies and representing IBM's future direction, and the System/36 line, intended for small companies who had used the company's legacy System/32/34 computers.
