  • The SCO Group filed a memorandum Friday in its lawsuit against IBM that indicates it needs more Unix code from IBM to detail its claims that Big Blue violated a contract between the two companies. IBM has provided SCO with some of the source code from its AIX and Dynix/ptx versions of Unix, but SCO now is requesting the source code underlying all intermediate versions of the software and the accompanying comments, logs and files from corporate programming tools.
