Now in many schools, institutes and other educational institutions you can find old computers that have already served their purpose both morally and physically. On such computers you can only study Dos, which is far from the realities of today. In addition, most people, as a rule, have a hard drive that is already inoperative. But it’s a shame to throw it away, but no one gives you new ones. Various sponsors and philanthropists sometimes give a computer (one) and rejoice like children. Thank you very much, of course, but, as you understand, this computer in general does not solve the problem, on the contrary, it makes it worse, I somehow don’t want to work on the old ones, now I just have something to compare with. But there is a way out of this situation. And it seems to me that it’s almost perfect.
