A medical history-taking device 20 for use by a patient is about the size of a book and has a screen 22 for displaying questions to a patient, a limited number of keys 26 by which the patient can enter answers, and a memory for storing the patient's answers. The device is battery-powered for portability and uses a low-power liquid crystal display or the like to display instructions and medical questions to the patient. Only four keys are seen or used by the patient for answering the questions: YES, NO, NOT SURE, and NEXT QUESTION. Additional control keys 36 used by the medical staff are hidden from the patient. The device is controlled by a pre-programmed microcomputer on a chip, and contains a ROM-based, removable and replaceable program cartridge 38b which contains the questions. The device collects the patient's answers, and drives a remote printer or computer terminal which provides an output of the medical history. <IMAGE>
