ANDOS is a Russian operating system for Electronika BK-0010, Electronika BK-0011 and Electronika BK-0011M series computers. It was created in 1990 and saw first release in 1992. Initially it was developed by Alexey Nadezhin (by whose name the system is named) and later also by Sergey Kamnev who joined the project. It was the only wide-spread system on BK series computers that used MS-DOS compatible file system format. ANDOS used FAT12 filesystem on 800Kb floppy disks. For Electronika BK-0011M and Electronika BK-0011 ANDOS provided Electronika BK-0010 emulation by loading BK-0010 ROM image into BK-0011(M) RAM. In minimal configuration the system was able to occupy less than 4 Kb of RAM.

The system was able to support up to 64 disk drives (or hard drive partitions) as well as RAM disks in the computer's memory and tape recording. It also was able to have read-only access to MicroDOS file system format disks, although in the last version this function was transferred from system core to the file manager and became optional.
