Addamax Inc last week announced that it has installed the world’s first System V.4/386 Compartmented Mode Workstation software at Contel Federal Systems in Virginia, and says it is in the process of shipping to 18 other customers in Europe, North America and the Far East. Addamax’s is the only Unix System V.4/386 system currently undergoing US government evaluation. Both Orange Book B1 and Compartmented Mode Workstation security ratings are being sought and the company expects to be on the General Services Adminstration schedule that gives the green light for government procurements to begin, by April. ACMW, as the software is called, reportedly supports both secure X Window and Open Look. A secure MS-DOS encapsulation capability will be released soon and secure networking is in process. Addamax president Peter Alsberg says the 4.0 Application Binary Interface assures that more than 800 applications available specifically for Unix System 4.0 as well as thousands of System V Interface Definition-compliant applications developed for Santa Cruz Operation Inc, Interactive Systems Corp and other versions of Unix will run on ACMW. The system is also Posix- and X/Open Portability Guide-compliant. Addamax’s beta customers are claimed to have verified the operation of 75 popular shrink-wrapped programs. The government is evaluating ACMW on 80386 machines from Zenith Data Systems, Delta Data Systems, Unisys Corp and Datawatch machines. Expectations are that Wang, Intel and others will be qualified thereafter along with 486 configurations.
