Programmable bootstrap loading system

摘要

A programmable bootstrap loader device for loading or transferring programs into the main memory of a computer system includes a processor-peripheral interface for decoding instructions of the computer system and for generating control signals to operate peripheral equipment coupled to the system. An alterable or programmable memory stores a set of instructions which makes up a bootstrap loader program, is not lost when power to the system is shut off. An alterable memory access circuit is coupled between the processor-peripheral interface and the alterable memory to enable an operator to alter discrete instructions of the stored bootstrap loader program.
