Abstract

Apparatus is provided for partitioning bulk storage into partitions having discrete address ranges where the size of each partination is programmable. This arrangement finds particular utility for using a single size of bulk storage for containing data to refresh multiple display devices having different size screens. For example, up to four display adapters could be attached to address one storage and the storage could be used to refresh two displays having 1920 characters, three screens having 960 characters or four screens having 480 characters. Any remaining storage, i.e., storage unassigned to the refresh function, is automatically accessible in another address range to be used for common tables and work space.
