The new Atari 1050 disk drive matched thenew high-tech, low profile line of Atari XL home computer systems. The original Atari 810 could hold singledensity data (88K out of 100K diskettes) which was standard. The new Atari 1050 disk drives wereDUAL-DENSITY disk drives and could use the older Atari 810 diskettes, but couldalso hold data in a new Enhanced Density mode of 127K. Although the standard for disk drives was180K, this additional storage was welcomed by Atari users who bought the diskdrives. The only downside tothe disk drives were their new version of Atari DOS: 3.0 which hadcompatibility problems with its earlier version: 2.0s Atari would later fix this problem with avery well designed and accepted and one of the most popular Atari versions ofDOS: 2.5 Up to 4 Atari diskdrives could be "daisy-chained" together. Using Atari's unique SIO bus (Serial I/O),each drive would connect to the next, forming a chain in which data wastransferred. Although slower thenother I/O buses used on other computers, Atari's SIO bus was a simple andconvenient way for the non-computer literate to more easily add components ontotheir Atari computer systems (other brands of computers required internalcards, ribbon cables, complicated jumper block settings which were geared moretowards the computer hobbyist crowd instead of the common individual withlittle computer knowledge). The disk driveelectronics and its mechanism were done by Tandon, the case design was done byTom Palecki, formerly of Atari's Industrial Design group. Tom was alsoresponsible for the design of the Atari 1055 3.5" disk drive which wasnever released by Atari, Inc. due to its sales in 1984.
