The ABCs of the Acorn Business Computer The Acorn Business Computer range is a family of computers designed to provide an entry level to suit every application, and with such a high degree of compatibility that any future expansion or diversification can be accommodated within the ABC family. To allow the user to tailor his system to accommodate his changing needs, a full range of supporting products will be available: 'mouse' interface, internally fitted communications modems, stand alone hard disc drives in a variety of capacities, and all necessary hardware for the implementation of Econet systems, either independent or multiple interlinked networks.
