SIO2Arduino is an Atari 8-bit (800/XL/XE) device emulator that runs on the Arduino platform. It currently emulates a single Atari 1050 disk drive (D1:) but there are plans to extend it to support multiple drives as well as other devices.

The SIO stands for the "Serial Input/Output". It is a data transfer protocol used by the Atari 8-bit machines to communicate with a printer, disk drive, modem etc. via the SIO connector. These transfers are controlled by the POKEY chip.

The board fits like an edge connector in between the two rows of pins in the Atari SIO port and is modeled after the Atari8Warez “Poor Mans SIO Cable”. The side labeled “SIO23V3” is the top/up side.
