Olympia Disque with IKBS¶
The Olympia Disque is an electronic daisywheel typwriter with single-line alphanumeric display, battery-buffered RAM and a proprietary 2" floppy disk drive.
It was possible to enable the Olympia Disque for Teletex, either with an internal add-on-board (IKBS) or with an external device.
