Abstract

PURPOSE: To designate the number of addresses larger than that which can be designated by the number of bits on IPL data, by designating indirectly device corresponding program storage start addresses by a set switch.
CONSTITUTION: An address designation switch is selected by a specific bit of IPL data, and the address of a ROM where a program is stored is designated by the address set on this switch. As a result, 4×4, namely, 16 device corresponding IPL program tables can be created by arranging four four-bit switches.
