The 1050 replaced the 810 in 1983, with a more compact design and larger storage capacity.
The Atari 1050 is a floppy disk drive for Atari 8-bit computers released in June 1983. It is compatible with the 90 kB single-density mode of the original Atari 810 it replaced, and added a new "enhanced" or "dual density" mode that provided 130 kB. Based on a half-height Tandon mechanism, it was smaller than the 810 and matched the styling of the new 600XL and 800XL machines.
The 1050 was styled to match the XL series of machines.
The 1200XL introduced Atari's new styling that the 1000-series peripherals matched.
The rear of the 1050 has a power jack on the right, two SIO ports (in and out) in the center, and the pin switches that select the drive number on the left.
