IS-DOS


iS-DOS is a disk operating system for Soviet/Russian ZX Spectrum clones. iS-DOS was developed in 1990 or 1991, by Iskra Soft, in Leningrad, Soviet Union, now Saint Petersburg, Russia.
It handles floppy disks, hard disk drives, and CD-ROMs. Maximum iS-DOS disk partitioning size on a hard disk is 16 MiB.
Unlike TR-DOS, iS-DOS is resident in random-access memory, and thus reduces the amount of memory available for user programs.

Versions

iS-DOS Chic is a version developed for the Nemo KAY. It provides more memory for user programs.
TASiS, based on iS-DOS Chic, is a modern version developed by NedoPC for the ATM Turbo 2+ in 2006, supports the enhanced text mode and larger memory of that model.
