Spectrum Concepts Inc, New York has a software system that will give Apple Macintosh computers unprecedented access to corporate communications networks, the firm claims. XCOM 6.2 for the Macintosh is based on IBM’s Advanced Program-to-Program Communications Logical Unit 6.2 specifications, and any XCOM 6.2 computer can exchange files, jobs and reports with any other XCOM 6.2 computer. XCOM 6.2 is available for IBM VTAM hosts, S/36, S/38, AS/400, MS-DOS and OS/2, DEC VAX, AT&T 3B2, Apollo and Sun workstations. XCOM 6.2 is claimed to be the first, and currently the only, Macintosh application to use MacAPPC and is compatible with SDLC, Token-Ring and AppleTalk. Due out in September, it costs $450, and needs MACAPPC installed.
