The Indus GT was a floppy disk drive made by Indus Systems of California, USA during the early 1980s for Apple II series and Atari home computer and later for the Commodore platforms of the day.  It came in a black casing with a smoke plexiglas cover over the drive mechanism. Behind the cover was an 8 segment LED track and sector display. It was considered as a high-quality unit, regarded by many as the best floppy drive available for 8-bit Ataris.  It was advertised as being over 400% faster than the Commodore 1541 and had an internal "ROM drive" with DOS utility commands,  but suffered from being less than 100% 1541 compatible.
