Just to clarify, they are using the cassettes and old computers to create punch cards required to run older machines they are using. They are also using modern equipment and computers. This is fairly common in industrial manufacturing because the cost of replacing or retrofitting expensive equipment is high not because older = better (although I'm sure sometimes that is the case).
