Development of software emulator for BESM-6, old soviet mainframe.
This project has been split and moved to:
https://github.com/besm6/simh - BESM-6 simulator
https://github.com/besm6/dispak - DISPAK simulator
https://github.com/besm6/besm6-archive - disk images
https://besm6.github.io/ - examples, DISPAK sources and KRAB sources
Essential historic emulator. Does the source code for the operating system exist anywhere?
