Abstract

An insertable element for the diskette or cassette station of a piece of electronic data processing equipment having an interface. The arrangement is such that data transmission between the EDP equipment and the element can be carried out through write/read devices which already exist in the EDP equipment. The element has a component which, in the inserted condition, is outside of the EDP equipment and itself is comprised of the EDP components and/or of the EDP devices and/or is constructed as a device to connect further EDP devices. According to another feature, a process for operating the EDP device with this insertable element is carried in such a way that the entire PC operating system and further programs are stored and at the commencement are loaded from there.
