Thank you for liking and following my #Prehistory of my homemade PERSEUS computers! More than 40 years ago, I did not think I would be able to make these my projects results available to you.

Are you sure? yes | no

Of course! It’s beautiful work. I really enjoy reading about it and seeing the photos of it.
