Abstract

A computer system as set forth in [*] has a slower operating master channel which can perform functions of the main channel so as to eliminate the need for a dedicated initial microprogram load (IMPL) device. When the master channel reads records from the save/restore file 5 (Fig. 1), it must either read the records contiguously during a number of revolutions or overrun occurs if an attempt is made to read the contiguous records in a single revolution. The present arrangement reduces the number of revolutions by reading the records in a scattered manner.
