Engineering:IS-DOS

iS-DOS is a disk operating system (DOS) for 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 (double sided, double density), hard disk drivess, and CD-ROMs. Maximum iS-DOS partition size on a hard disk is 16 MiB.

Unlike TR-DOS, iS-DOS is random-access memory (RAM) based. Such operating systems reduce the amount of memory available for user programs.

Versions

iS-DOS Chic is a version developed for Nemo KAY. It provides more memory for user programs.

TASiS, based on iS-DOS Chic, is a modern version developed by NedoPC for ATM Turbo 2+ in 2006. It supports text mode and high memory of that machine.
