The claims made on that web page are true. There have been several attempts to rebuild one of his machines. One of them used to be shown in the Technikmuseum in Berlin, but apparently it has been moved to the Konrad Zuse Museum in Hünich.
The machine used binary arithmetic and could do floating point addition (0.8 seconds) and multiplication (3 seconds) and had 64 22-bit words of memory. It's actually quite a technological marvel considering it was built in the war and he had trouble getting the materials to build it as military projects were prioritized and the Nazis didn't consider his machine important for the war effort.
