The Proxa 7000 expansion was made by the German company Ultra Electronic. It adds CBM 8000 series compatibility to the CBM 700 series. For a long time nobody could use this rare expansion because the software was missing. But recently the software was found. You can read more about this very rare expansion on Steve Gray's Commodore web page.
