(through Unisoft) in early 1989, SOX was one of the first re-implementation of UNIX fully independent of AT&T
that passed the X/Open
verification tests, and the only one ever completed 100% outside the United States
.
SOX was designed to run on COBRA's own minicomputer
s and was part of Brazilian Informatics Policy that aimed to achieve technological independence from the United States
