An East German built this computer using a book back in the early 80s. He had to make trips to West Berlin to buy the RAM chips using a day pass. It's a Z80 clone based around the MME U880.

Are there digital copies of this book? I am planning on doing a similar thing


@waweic @zpojqwfejwfhiunz I may have a later copy of that book as paper, buried somewhere in my storage. We used GDR books about U880 (=Z80) b/c the german Explanations were sometimes easier for us than the english books.

@waweic @zpojqwfejwfhiunz But you won‘t need that book for the looks. Just dig into 1980s microprocessor stuff. There‘s plenty.

For anyone want to design/make their own computer, just google "homebrew CPU", or "homebrew computer".
Many people around the world have already done it and shared everything publicly.
During cold war, Cray-1 was copied by China, and iron curtain countries copied PDP machines a lot.
