There is a way to see many old computers running in one room in Czech Republic. It’s called Bytefest and it is probably the biggest public retrocomputing event in the country. I took about twenty computers in my car with me this year in order to show the evolution of portable computers.
There were a lot of people walking around and some of them brought their kids. It is somehow nice to see little kids trying to do something with computers that are few decades older than they are. When they grow up there is a high chance that these computers will not work anymore.
