NCR, Honeywell, Control Data and Xerox have all done it, so if a company aspires to the Big League, it must be a desirable move – it being driving one’s essential maintenance operations harder by throwing them open to third party products, and Harris Corp has just taken the plunge in the US. The Melbourne, Florida company’s Customer Support operation will primarily target IBM and DEC sites, and is not concerned that users have any Harris kit. It will support everything, including telecommunications equipment, except mainframes. It looks for the third party business to generate $1.5m to $2m this year, and to grow it to some $5m in 1988.
