Atari 815 disk drive

Created in 1981, this was Atari's first double density disk drive.  The 815 utilized both MPI and Tandon mechanisms and had both versions of the front plastic panels to support either drive.  The 815 is nearly as tall as 2 810s stack on top of each other.  Few catalogs ever displayed the Atari 815.  It sold for $1,500.00 in very limited quantities and thus never went into full production.
