– Data Bank Western Digital, (Irvine, California) – FileCard Tandy 1000 Hard cards were the most desirable and easiest way to add a hard drive to the original Tandy 1000 lines that had 8-bit slots such as the Sx, Tx, Sl, Tl series. However Tandy offered a size reduced 10.5-in slot, where as Plus hard cards took a full length 13 inches. Hence Plus development hardcards are not physically compatible, as they are too long to fit in a Tandy 1000 computer. If the cover is removed, and the metal plate is removed so that a Plus Development card could fit in physically, it would work normally. Acquisitions Over the eight years of its existence, Plus Development had only a single acquisition, La Cie, of Tualatin, Oregon, a manufacturer and direct marketeer of external hard drives for Apple Computer products. The trade paper InfoWorld published the announcement in their December 3, 1990, edition noting the $3.8 million cash transaction.
