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.
