Abstract
A light source apparatus for an endoscope comprises a light source for supplying light to the endoscope for illuminating an object, a microcomputer for effecting operation control, and an erasable programmable read only memory for storing data that is used in the microcomputer. The read only memory may be replaced with a access memory that has a chip select terminal connected to a programmable input/output interface, which is connected to a system bus of the microcomputer, in such a manner that the random access memory will not be selected when all output ports of the interface are set to either a high or low level.
