Very little information about this Bulgarian mainframe used by big East European companies as an industrial or information management system.
It was partially compatible with IBM mainframe and could also share programs and data with the russian Minsk-32. It could run in multiprogram mode thanks to its virtual memory.
The ISOT brand name means 'State Economic Alliance'
Thanks to Bojidar Stefanov for information and picture.
We need more info about this computer ! If you designed, used, or have more info about this system,

Please consider donating your old computer / videogame system to Old-Computers.com or one of our partners from anywhere in the world (Europe, America, Asia, etc.).
This was an IBM370 series compatible computer. We used it with IBM-DOS/VS-POWER system.
