-During my BK-0010-01 demonstration, I will shortly tell about computers' usage in SU in 1980s (at organizations, in schools and at home). I will show BK-0010-01 most common usage cases and some games, using a real cassette recorder. Then, I will demonstrate how everything changed when a floppy controller had been released, operating systems (and shortly describe their internals) and other application software used in 1985-1999 on BK-0010-01. I will also tell visitors other controllers developed for this set of computers and usage cases in education.+During my BK-0010-01 demonstration, I will shortly tell about computers' usage in SU in 1980s (at organizations, in schools and at home).
