iS-DOS

iS-DOS is a <a href="/facts/Disk_operating_system/Kc28g5MR">disk operating system</a> (DOS) for Soviet/Russian <a href="/facts/List_of_ZX_Spectrum_clones/gBj9Ce2c">ZX Spectrum clones</a>. iS-DOS was developed in 1990 or 1991, by Iskra Soft, in Leningrad, <a href="/facts/Soviet_Union/m7wWsPto">Soviet Union</a>, now <a href="/facts/Saint_Petersburg/pNuCBxaM">Saint Petersburg</a>, <a href="/facts/Russia/jfkCwyxn">Russia</a>.
It handles <a href="/facts/Floppy_disk/rShxfuxa">floppy disks</a> (double sided, double density), <a href="/facts/Hard_disk_drive/kekLSGSE">hard disk drives</a>, and <a href="/facts/CD-ROM/JwuaYLJv">CD-ROMs</a>.

Unlike <a href="/facts/TR-DOS/IfPQm9fl">TR-DOS</a>, iS-DOS is resident in <a href="/facts/Random-access_memory/DuD4bxh6">random-access memory</a> (RAM), and thus reduces the amount of memory available for user programs.
